readDatasets {rpact}R Documentation

Read Multiple Datasets

Description

Reads a data file and returns it as a list of dataset objects.

Usage

readDatasets(
  file,
  ...,
  header = TRUE,
  sep = ",",
  quote = "\"",
  dec = ".",
  fill = TRUE,
  comment.char = "",
  fileEncoding = "UTF-8"
)

Arguments

file

A CSV file (see read.table).

...

Further arguments to be passed to read.table.

header

A logical value indicating whether the file contains the names of the variables as its first line.

sep

The field separator character. Values on each line of the file are separated by this character. If sep = "," (the default for readDatasets) the separator is a comma.

quote

The set of quoting characters. To disable quoting altogether, use quote = "". See scan for the behavior on quotes embedded in quotes. Quoting is only considered for columns read as character, which is all of them unless colClasses is specified.

dec

The character used in the file for decimal points.

fill

logical. If TRUE then in case the rows have unequal length, blank fields are implicitly added.

comment.char

character: a character vector of length one containing a single character or an empty string. Use "" to turn off the interpretation of comments altogether.

fileEncoding

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'.

Details

Reads a file that was written by writeDatasets before.

Value

Returns a list of Dataset objects.
