write.arff: Writes data to ARFF

In rmcfs: The MCFS-ID Algorithm for Feature Selection and Interdependency Discovery

Description

Exports data into ARFF format. This format is used by Weka Data Mining software http://www.cs.waikato.ac.nz/ml/weka/.

Usage

write.arff(x, file = "", target = NA, chunk_size=100000, zip = FALSE)

Arguments

x	data frame with data
file	exported filename
target	sets target attribute in ARFF format. Default value is NA what refers to the last column.
chunk_size	it defines size of chunk (number of cells) that are processed and exported. The bigger the value, the function is faster for small data and slower for big data.
zip	whether to create zip archive.

Examples

  ## Not run: ###dontrunbegin

  # create artificial data
  adata <- artificial.data(rnd_features = 1000)
  
  #Fix input data to be consistent with ARFF and ADX formats. 
  #It is not necessary but for some data can help to export in proper format.
  adata <- fix.data(adata)
  write.arff(adata, file = file.path(tempdir(), "adata.arff"), target = "class")
  
  
## End(Not run)###dontrunend
