Package 'Hmisc' - R

44 csv.get
Arguments
file
lowernames
datevars
the file name for import.
set this to TRUE to change variable names to lower case.
character vector of names (after lowernames is applied) of variables to consider
as a factor or character vector containing dates in a format matching dateformat.
The default is "%F" which uses the yyyy-mm-dd format.
datetimevars character vector of names (after lowernames is applied) of variables to consider
to be date-time variables, with date formats as described under datevars
followed by a space followed by time in hh:mm:ss format. chron 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.
dateformat
fixdates
for cleanup.import is the input format (see strptime)
for any of the variables listed in datevars that have a dateformat that
cleanup.import understands, specifying fixdates allows corrections of
certain formatting inconsistencies before the fields are attempted to be converted
to dates (the default is to assume that the dateformat is followed
for all observation for datevars). Currently fixdates=’year’ is implemented,
which will cause 2-digit or 4-digit years to be shifted to the alternate
number of digits when dateform is the default "%F" or is "%y-%m-%d",
"%m/%d/%y", or "%m/%d/%Y". Two-digits years are padded with 20 on the
left. Set dateformat to the desired format, not the exceptional format.
comment.char a character vector of length one containing a single character or an empty string.
Use ’""’ to turn off the interpretation of comments altogether.
autodates
allow
charfactor
sep
skip
vnames
labels
Set to true to allow function to guess at which variables are dates
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.
set to TRUE to change character variables to factors if they have at least two
characters in an observation but have fewer than n/2 unique values
field separator, defaults to comma
number of records to skip before data start. Required if vnames or labels is
given.
number of row containing variable names, default is one
number of row containing variable labels, default is no labels
... arguments to pass to read.csv other than skip and sep.
Details
csv.get reads comma-separated text data files, allowing optional translation to lower case for
variable names after making them valid S names. Original possibly non-legal names are taken to
be variable labels if labels is not specified. Character or factor variables containing dates can be
converted to date variables. cleanup.import is invoked to finish the job.
