View source: R/writeARFF.R

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.

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

`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.
