qdap-tm Package Compatibility
No full textThe qdap package (Rinker, 2013) is an R package designed to assist in quantitative discourse analysis. The package stands as a bridge between qualitative transcripts of dialogue and statistical analysis and visualization. The tm package (Feinerer and Hornik, 2014) is a major R (R Core Team, 2013) package used for a variety of text mining tasks. Many text analysis packages have been built around the tm package’s infrastructure (see CRAN Task View: Natural Language Processing). As qdap aims to act as a bridge to other R text mining analyses it is important that qdap provides a means of moving between the various qdap and tm data types. This vignette serves as a guide towards navigating between the qdap and tm packages. Specifically, the two goals of this vignette are to (1) describe the various data formats of the two packages and (2) demonstrate the use of qdap functions that enable the user to move seamlessly between the two packages. 1

</li>
</ul>
<p><strong>BUG FIXES</strong></p>
<ul>
<li><p>rm_number did not extract consecutive digits that aren't comma separated
without separating it into multiple strings. For example "12345" became
"123" "45". Also 444,44 will not be removed/extracted as it is not a valid
comma separated number. These behavior have been corrected and the unit test
now include these cases. Thanks to Jason Gray for the reworked of the regex.
It is simpler and more accurate.</p></li>
<li><p>rm_between did not handle quotation marks (") as both the left and right
boundary when extract = TRUE. Bug reported by Tori Shannon,
<a href="http://stackoverflow.com/q/31119989/1000343,"></a><a href="http://stackoverflow.com/q/31119989/1000343">http://stackoverflow.com/q/31119989/1000343</a>, and addressed by Jason Gray. See
<a href="https://github.com/trinker/qdapRegex/issues/13">issue #13</a></p></li>
</ul>
<p><strong>NEW FEATURES</strong></p>
<ul>
<li><p>as_numeric & as_numeric2 added for use with rm_number. These are
wrappers for as.numeric(gsub(",", "", x)). The former removes commas and
converts a list of vectors of strings to numeric. The later wraps
as_numeric with unlist.</p></li>
<li><p>rm_non_words added to remove every any character that isn't a letter,
apostrophe, or single space.</p></li>
<li><p>The class extracted has been added and is the output of a rm_xxx function
when extract = TRUE. This allows for the c.extracted function to easily
turn the list output into a character vector.</p></li>
<li><p>c.extracted added to provide a quick unlist method for lists of class
extracted. The is less typing than unlist for an approach that is used
often.</p></li>
<li><p>bind_or added as a means of quickly wrapping multiple sub-expression
elements with left/right boundaries and then concatenate/joins the grouped
strings with regular expression or statement ("|").</p></li>
</ul>
<p><strong>MINOR FEATURES</strong></p>
<ul>
<li>
punctuation added to regex_supplement dictionary for easy negation of
[:punct:] class.</li>

<p><strong>BUG FIXES</strong></p>
<ul>
<li><p>explain used message to print to the console. explain now returns an
object of the class explain with its own print method which uses cat
rather than message. Additionally, the characters + and & were not
handled correctly; this has been corrected.</p></li>
<li><p>Documentation for TC "there is an incomplete sentence. It is as follows:
TC utilizes additional rules for capitalization beyond stri_trans_totitle
that includes..." (found by rmsharp). This has been corrected. See <a href="https://github.com/trinker/qdapRegex/issues/8">issue #8</a></p></li>
<li><p>cheat (and accompanying regex_cheat dictionary) contained misspellings in
the words <em>greedy</em> and <em>beginning</em>. This has been corrected.</p></li>
<li><p>rm_number incorrectly handled numbers containing leading or trailing zeros.
See <a href="https://github.com/trinker/qdapRegex/issues/9">issue #9</a></p></li>
<li><p>rm_caps_phrases could only extract/remove up to two "words" worth of capital
letter phrases at a time. See <a href="https://github.com/trinker/qdapRegex/issues/11">issue #11</a></p></li>
</ul>
<p><strong>NEW FEATURES</strong></p>
<ul>
<li><p>%+% binary operator version of pastex(x, y, sep = "") added to join
regular expressions together.</p></li>
<li><p>group_or added as a means of quickly wrapping multiple sub-expression
elements with grouping parenthesis and then concatenate/joins the grouped
strings with regular expression or statement ("|").</p></li>
<li><p>rm_repeated_characters added for removing/extracting/replacing words with
repeated characters (each repeated > 2 times). Regex pattern comes from:
StackOverflow's vks (<a href="http://stackoverflow.com/a/29438461/1000343)."></a><a href="http://stackoverflow.com/a/29438461/1000343">http://stackoverflow.com/a/29438461/1000343</a>).</p></li>

into chunks.</li>
</ul>
<p><strong>IMPROVEMENTS</strong></p>
<ul>
<li><p>Regular Expression Dictionaries (e.g., regex_usa and regex_supplement) are
now managed with the <strong>regexr</strong> package. This enables cleaner updating of the
regular expressions with easier to read structure. Longer files will be
stored in this format. Files located:

</ul>
<p><strong>BUG FIXES</strong></p>
<ul>
<li><p>pastex would throw a warning on a vector (e.g., pastex(letters)). This
has been fixed.</p></li>
<li><p>youtube_id was documented under qdap_usa rather than qdap_supplement and
contained an invalid hyperlink. This has been fixed.</p></li>
<li><p>rm_citation contained a bug that would not operate on citations with a comma
in multiple authors before the and/& sign. See <a href="https://github.com/trinker/qdapRegex/issues/4">issue #4</a></p></li>
</ul>
<p><strong>NEW FEATURES</strong></p>

<ul>
<li><p>last_occurrence regex added to the regex_supplement dictionary to find the
last occurrence of delimiter.</p></li>
<li><p>word_boundary, word_boundary_left, and word_boundary_right added to
regex_supplement dictionary to provide a true word boundary. Regexes
adapted from: <a href="http://www.rexegg.com/regex-boundaries.html#real-word-boundary"></a><a href="http://www.rexegg.com/regex-boundaries.html#real-word-boundary">http://www.rexegg.com/regex-boundaries.html#real-word-boundary</a></p></li>
<li><p>rm_time2 regex added to the regex_usa dictionary to find time + AM/PM</p></li>
</ul>
<p><strong>IMPROVEMENTS</strong></p>
<ul>
<li><p>The regex_usa dictionary regular expressions: rm_hash, rm_tag, rm_tag2
and rm_between pick up grouping that allows for replacement of individual
sections of the substring. See ?rm_hash and ?rm_tag for examples.</p></li>

<li><code>rm_between</code> did not handle single quotation marks (<code>'</code>) as both the left and
right boundary when <code>extract = TRUE</code>. Related to <a href="https://github.com/trinker/qdapRegex/issues/13">issue #13</a></li>
</ul>
<p><strong>NEW FEATURES</strong></p>
<ul>
<li><p><code>rm_transcript_time</code> added to remove transcript specific style of time stamp
tagging. See <a href="http://help-nv10mac.qsrinternational.com/desktop/procedures/import_audio_or_video_transcripts.htm" target="_blank">http://help-nv10mac.qsrinternational.com/desktop/procedures/import_audio_or_video_transcripts.htm</a> for details.</p>
</li>
<li><p><code>as_time</code> and <code>as_time2</code> added for use with <code>rm_time</code>/<code>rm_time_trnscript</code>.<br>
These are convert to the standard HH:MM:SS.OS format and optionally converts
to <code>as.POSIXlt</code>. The former outputs a list of vectors of times while the
later wraps <code>as_time</code> with <code>unlist</code>.</p>
</li>
</ul>
<p><strong>MINOR FEATURES</strong></p>
<ul>
<li><p><code>except_first</code> added to <code>regex_supplement</code> dictionary to provide a means to
remove all occurrences of a character except the first appearance. Regex
from: <a href="http://stackoverflow.com/a/31458261/1000343" target="_blank">http://stackoverflow.com/a/31458261/1000343</a></p>
</li>
<li><p><code>rm_between</code> and <code>r_between_multiple</code> pick up a <code>fixed</code> argument. Previously,
<code>left</code> and <code>right</code> boundaries containing regular expression special characters
were fixed by default (escaped). This did not allow for the powerful use of a
regular expression for left/right boundaries. The <code>fixed = TRUE</code> behavior
is still the default but users can now set <code>fixed = FALSE</code> to work with
regular expression boundaries. This new feature was inspired by @Ronak Shah's
StackOverflow question: <a href="http://stackoverflow.com/q/31623069/1000343" target="_blank">http://stackoverflow.com/q/31623069/1000343</a></p>
</li>
</ul>
<p><strong>CHANGES</strong></p>
<ul>
<li><p><code>word_boundary</code>, <code>word_boundary_left</code>, <code>word_boundary_right</code> regexes in the
<code>regex_supplement</code> did not include apostrophes as a viable word character.
Apostrophes are now included as a word character.</p>
</li>
<li><p><code>explain</code> no longer prints the regular expression explanation to the command
line. Instead the link to <a href="http://www.regexper.com" target="_blank">http://www.regexper.com</a> is printed. This change
is because <a href="http://rick.measham.id.au/paste/explain" target="_blank">http://rick.measham.id.au/paste/explain</a> no longer appears to be
working. The text explanation functionality will return if the website
becomes operational again or if a suitable substitute can be found.</p>
<p><a href="https://github.com/trinker/qdapRegex" target="_blank">qdapRegex</a> 0.4.0</p>
</li>
</ul>
<p><strong>BUG FIXES</strong></p>
<ul>
<li><p><code>rm_number</code> did not extract consecutive digits that aren't comma separated
without separating it into multiple strings. For example "12345" became
"123" "45". Also 444,44 will not be removed/extracted as it is not a valid
comma separated number. These behavior have been corrected and the unit test
now include these cases. Thanks to Jason Gray for the rework of the regex.
It is simpler and more accurate.</p>
</li>
<li><p><code>rm_between</code> did not handle quotation marks (<code>"</code>) as both the left and right
boundary when <code>extract = TRUE</code>. Bug reported by Tori Shannon,
<a href="http://stackoverflow.com/q/31119989/1000343," target="_blank">http://stackoverflow.com/q/31119989/1000343,</a> and addressed by Jason Gray. See
<a href="https://github.com/trinker/qdapRegex/issues/13">issue #13</a></p>
</li>
</ul>
<p><strong>NEW FEATURES</strong></p>
<ul>
<li><p><code>as_numeric</code> & <code>as_numeric2</code> added for use with <code>rm_number</code>. These are
wrappers for <code>as.numeric(gsub(",", "", x))</code>. The former removes commas and
converts a list of vectors of strings to numeric. The later wraps
<code>as_numeric</code> with <code>unlist</code>.</p>
</li>
<li><p><code>rm_non_words</code> added to remove every any character that isn't a letter,
apostrophe, or single space.</p>
</li>
<li><p>The class <code>extracted</code> has been added and is the output of a <code>rm_xxx</code> function
when <code>extract = TRUE</code>. This allows for the <code>c.extracted</code> function to easily
turn the <code>list</code> output into a character vector.</p>
</li>
<li><p><code>c.extracted</code> added to provide a quick unlist method for <code>list</code>s of class
<code>extracted</code>. The is less typing than <code>unlist</code> for an approach that is used
often.</p>
</li>
<li><p><code>bind_or</code> added as a means of quickly wrapping multiple sub-expression
elements with left/right boundaries and then concatenate/joins the grouped
strings with regular expression or statement ("|").</p>
</li>
</ul>
<p><strong>MINOR FEATURES</strong></p>
<ul>
<li><code>punctuation</code> added to <code>regex_supplement</code> dictionary for easy negation of
<code>[:punct:]</code> class.</li>
</ul>
<a href="https://github.com/trinker/qdapRegex" target="_blank">qdapRegex</a> 0.2.1 - 0.3.2
<p><strong>BUG FIXES</strong></p>
<ul>
<li><p><code>explain</code> used <code>message</code> to print to the console. <code>explain</code> now returns an
object of the class <code>explain</code> with its own print method which uses <code>cat</code>
rather than <code>message</code>. Additionally, the characters <code>+</code> and <code>&</code> were not
handled correctly; this has been corrected.</p>
</li>
<li><p>Documentation for <code>TC</code> "there is an incomplete sentence. It is as follows:
TC utilizes additional rules for capitalization beyond <code>stri_trans_totitle</code>
that includes..." (found by rmsharp). This has been corrected. See <a href="https://github.com/trinker/qdapRegex/issues/8">issue #8</a></p>
</li>
<li><p><code>cheat</code> (and accompanying <code>regex_cheat</code> dictionary) contained misspellings in
the words <em>greedy</em> and <em>beginning</em>. This has been corrected.</p>
</li>
<li><p><code>rm_number</code> incorrectly handled numbers containing leading or trailing zeros.
See <a href="https://github.com/trinker/qdapRegex/issues/9">issue #9</a></p>
</li>
<li><p><code>rm_caps_phrases</code> could only extract/remove up to two "words" worth of capital
letter phrases at a time. See <a href="https://github.com/trinker/qdapRegex/issues/11">issue #11</a></p>
</li>
</ul>
<p><strong>NEW FEATURES</strong></p>
<ul>
<li><p><code>%+%</code> binary operator version of <code>pastex(x, y, sep = "")</code> added to join
regular expressions together.</p>
</li>
<li><p><code>group_or</code> added as a means of quickly wrapping multiple sub-expression
elements with grouping parenthesis and then concatenate/joins the grouped
strings with regular expression or statement ("|").</p>
</li>
<li><p><code>rm_repeated_characters</code> added for removing/extracting/replacing words with
repeated characters (each repeated > 2 times). Regex pattern comes from:
StackOverflow's vks (<a href="http://stackoverflow.com/a/29438461/1000343)." target="_blank">http://stackoverflow.com/a/29438461/1000343).</a></p>
</li>
<li><p><code>rm_repeated_phrases</code> added for removing/extracting/replacing repeating
phrases (> 2 times). Regex pattern comes from:
StackOverflow's BrodieG (<a href="http://stackoverflow.com/a/28786617/1000343)." target="_blank">http://stackoverflow.com/a/28786617/1000343).</a></p>
</li>
<li><p><code>rm_repeated_words</code> added for removing/extracting/replacing repeating words
(> 2 times).</p>
</li>
</ul>
<p><strong>MINOR FEATURES</strong></p>
<ul>
<li><code>run_split</code> regex added to the <code>regex_supplement</code> dictionary to split runs
into chunks.</li>
</ul>
<p><strong>IMPROVEMENTS</strong></p>
<ul>
<li><p>Regular Expression Dictionaries (e.g., <code>regex_usa</code> and <code>regex_supplement</code>) are
now managed with the <strong>regexr</strong> package. This enables cleaner updating of the
regular expressions with easier to read structure. Longer files will be
stored in this format. Files located:
<a href="https://github.com/trinker/qdapRegex/tree/master/inst/regex_scripts">https://github.com/trinker/qdapRegex/tree/master/inst/regex_scripts</a></p>
</li>
<li><p><code>rm_caps_phrase</code> has a new regular expression that is more accurate and does
not pull trailing white space.</p>
</li>
</ul>

<p><strong>BUG FIXES</strong></p>
<ul>
<li><p><code>pastex</code> would throw a warning on a vector (e.g., <code>pastex(letters)</code>). This
has been fixed.</p>
</li>
<li><p><code>youtube_id</code> was documented under <code>qdap_usa</code> rather than <code>qdap_supplement</code> and
contained an invalid hyperlink. This has been fixed.</p>
</li>
<li><p><code>rm_citation</code> contained a bug that would not operate on citations with a comma
in multiple authors before the and/& sign. See <a href="https://github.com/trinker/qdapRegex/issues/4">issue #4</a></p>
</li>
</ul>
<p><strong>NEW FEATURES</strong></p>

</li>
<li><p><code>explain</code> added to view a visual representation of a regular expression using
<a href="http://www.regexper.com" target="_blank">http://www.regexper.com</a> and <a href="http://rick.measham.id.au/paste/explain." target="_blank">http://rick.measham.id.au/paste/explain.</a> Also
takes named regular expressions from the <code>regex_usa</code> or other supplied
dictionary.</p>
</li>
</ul>
<p><strong>MINOR FEATURES</strong></p>
<ul>
<li><p><code>last_occurrence</code> regex added to the <code>regex_supplement</code> dictionary to find the
last occurrence of delimiter.</p>
</li>
<li><p><code>word_boundary</code>, <code>word_boundary_left</code>, and <code>word_boundary_right</code> added to
<code>regex_supplement</code> dictionary to provide a true word boundary. Regexes
adapted from: <a href="http://www.rexegg.com/regex-boundaries.html#real-word-boundary" target="_blank">http://www.rexegg.com/regex-boundaries.html#real-word-boundary</a></p>
</li>
<li><p><code>rm_time2</code> regex added to the <code>regex_usa</code> dictionary to find time + AM/PM</p>
</li>
</ul>
<p><strong>IMPROVEMENTS</strong></p>
<ul>
<li><p>The <code>regex_usa</code> dictionary regular expressions: <code>rm_hash</code>, <code>rm_tag</code>, <code>rm_tag2</code>
and <code>rm_between</code> pick up grouping that allows for replacement of individual
sections of the substring. See <code>?rm_hash</code> and <code>?rm_tag</code> for examples.</p>
</li>
<li><p><code>pastex</code> picks up a <code>sep</code> argument to allow the user to choose what string
is used to separate the collapsed expressions.</p>
</li>
<li><p><code>rm_citation</code>, <code>rm_citation2</code>, and <code>rm_citation3</code> now attempt to include last
names that contain the lower case particles: von, van, de, da, and du.</p>
</li>
</ul>
