Reads a data file and returns it as dataset object.
readDataset(file, ..., header = TRUE, sep = ",", quote = "\"",
dec = ".", fill = TRUE, comment.char = "", fileEncoding = "UTF-8")
A CSV file (see read.table
).
Further arguments to be passed to coderead.table.
A logical value indicating whether the file contains the names of the variables as its first line.
The field separator character. Values on each line of the file are separated
by this character. If sep = "," (the default for readDataset
) the separator is a comma.
The set of quoting characters. To disable quoting altogether, use
quote = "". See scan for the behaviour on quotes embedded in quotes. Quoting is only
considered for columns read as character, which is all of them unless colClasses
is specified.
The character used in the file for decimal points.
logical. If TRUE
then in case the rows have unequal length, blank fields
are implicitly added.
character: a character vector of length one containing a single character or an empty string. Use "" to turn off the interpretation of comments altogether.
character string: if non-empty declares the encoding used on a file (not a connection) so the character data can be re-encoded. See the 'Encoding' section of the help for file, the 'R Data Import/Export Manual' and 'Note'.

and puts the data to getDataset
.

for reading multiple datasets,
writeDataset
for writing a single dataset,
writeDatasets
for writing multiple datasets.
