Read comma-separated text data files, allowing optional translation
 to lower case for variable names after making them valid S names.
 There is a facility for reading long variable labels as one of the
 rows. If labels are not specified and a final variable name is not
 the same as that in the header, the original variable name is saved as
 a variable label. Uses <code>read.csv</code> if the <code>data.table</code>
	package is not in effect, otherwise calls <code>fread</code>.

csv.get

Contains many functions useful for data
analysis, high-level graphics, utility operations, functions for
computing sample size and power, simulation, importing and annotating datasets,
imputing missing values, advanced table making, variable clustering,
character string manipulation, conversion of R objects to Typst, LaTeX, and html code,
recoding variables, caching, simplified parallel computing, encrypting and decrypting data using a safe workflow, general moving window statistical estimation, and assistance in interpreting principal component analysis.

csv.get function

Read Comma-Separated Text Data Files — csv.get

<dl>

 <dt>file</dt>
<dd>the file name for import.</dd>

 <dt>lowernames</dt>
<dd>set this to <code>TRUE</code> to change variable names to
 lower case.</dd>

 <dt>datevars</dt>
<dd>character vector of names (after <code>lowernames</code> is
 applied) of variables to consider as a factor or character vector
 containing dates in a format matching <code>dateformat</code>. The
 default is <code>"%F"</code> which uses the yyyy-mm-dd format.</dd>

 <dt>datetimevars</dt>
<dd>character vector of names (after <code>lowernames</code>
	is applied) of variables to consider to be date-time variables, with
	date formats as described under <code>datevars</code> followed by a space
	followed by time in hh:mm:ss format. <code>chron</code> is used to store
	such variables. If all times in the variable
	are 00:00:00 the variable will be converted to an ordinary date variable.</dd>

 <dt>dateformat</dt>
<dd>for <code>cleanup.import</code> is the input format (see
 <code><a href='https://rdrr.io/r/base/strptime.html'>strptime</a></code>)</dd>

 <dt>fixdates</dt>
<dd>for any of the variables listed in <code>datevars</code>
 that have a <code>dateformat</code> that <code>cleanup.import</code> understands,
 specifying <code>fixdates</code> allows corrections of certain formatting
 inconsistencies before the fields are attempted to be converted to
 dates (the default is to assume that the <code>dateformat</code> is followed
 for all observation for <code>datevars</code>). Currently
 <code>fixdates='year'</code> is implemented, which will cause 2-digit or
 4-digit years to be shifted to the alternate number of digits when
 <code>dateform</code> is the default <code>"%F"</code> or is <code>"%y-%m-%d"</code>,
 <code>"%m/%d/%y"</code>, or <code>"%m/%d/%Y"</code>. Two-digits years are
	padded with <code>20</code> on the left. Set <code>dateformat</code> to the
	desired format, not the exceptional format.</dd>

 <dt>comment.char</dt>
<dd>a character vector of length one containing a
 single character or an empty string. Use '""' to turn off the
 interpretation of comments altogether.</dd>

 <dt>autodate</dt>
<dd>Set to true to allow function to guess at which
 variables are dates</dd>

 <dt>allow</dt>
<dd>a vector of characters allowed by R that should not be
 converted to periods in variable names. By default, underscores in
 variable names are converted to periods as with R before version
 1.9.</dd>

 <dt>charfactor</dt>
<dd>set to <code>TRUE</code> to change character variables to
	factors if they have fewer than n/2 unique values. Blanks and null
	strings are converted to <code>NA</code>s.</dd>

 <dt>sep</dt>
<dd>field separator, defaults to comma</dd>

 <dt>skip</dt>
<dd>number of records to skip before data start. Required if
	<code>vnames</code> or <code>labels</code> is given.</dd>

 <dt>vnames</dt>
<dd>number of row containing variable names, default is one</dd>

 <dt>labels</dt>
<dd>number of row containing variable labels, default is no
		labels</dd>

	<dt>text</dt>
<dd>a character string containing the <code>.csv</code> file to use
		instead of <code>file=</code>. Passed to <code>read.csv</code> as the
		<code>text=</code> argument.</dd>

 <dt>...</dt>
<dd>arguments to pass to <code>read.csv</code> other than
	<code>skip</code> and <code>sep</code>.</dd>
