farff (version 1.1.1)

writeARFF: Write ARFF data.frame to ARFF file.

Description

Internally uses write.table and is therefore not much faster than RWeka's write.arff. Moreover, for large data (> 1e6 rows) the date frame is written out in chunks of 1e6 lines to speed up the write process.

Usage

writeARFF(
  x,
  path,
  overwrite = FALSE,
  chunk.size = 1e+06,
  relation = deparse(substitute(x))
)

Arguments

x

[data.frame] Data to write to disk.

path

[character(1)] Path to ARFF file with write access. Existing files will not be overwritten unless overwrite is TRUE.

overwrite

[logical(1)] Should path be overwritten if it already exists? Default is FALSE.

chunk.size

[integer(1)] Large datesets are split before writing out to file into chunks of size chunk.size. Default is 1e6.

relation

[character(1)] Name of the relation in the ARFF file. Default is to guess it from the object name.

Value

Nothing.

Examples

# NOT RUN {
# see readARFF
