write.arff
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. |
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.
