write.adh: Writes data to ADH

Description

Exports data into ADH format. This format is based on two files: 'adh' that contains ADX header and 'csv' that contains the data.

Usage

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

Arguments

x

data frame with data

file

exported filename

target

sets target attribute in ADH format. Default value is NA what refers to the last column.

chunk_size

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

  if (FALSE) ###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.adh(adata, file = file.path(tempdir(), "adata.adh"), target = "class")
