Write Data into ARFF Files

Description

Writes data into Weka Attribute-Relation File Format (ARFF) files.

Usage

write.arff(x, file, eol = "\n", relation = deparse(substitute(x)))

Arguments

x

the data to be written, preferably a matrix or data frame. If not, coercion to a data frame is attempted.

file

either a character string naming a file, or a connection. "" indicates output to the standard output connection.

eol

the character(s) to print at the end of each line (row).

relation

The name of the relation to be written in the file.

Details

relation will be passed through make.names before writing to the file, in an attempt to it them acceptable to Weka, and column names what do not start with an alphabetic character will have X prepended.

However, the references say that ARFF files are ASCII files, and that encoding is not enforced.
