In aydindemircioglu/SVMBridge: A Bridge to Integrate Different 'SVM' Solvers into R

Description

Write given (dense) R matrix and R vector in sparse (LIBSVM) format to given file.

Usage

writeSparseData(filename, X, Y, append = FALSE, skipBytes = 0L,
  verbose = FALSE, zeroBased = FALSE)

Arguments

filename	the filename to write the given data to
X	The data to write as a matrix
Y	The labels for the data.
append	Append to the file (or overwrite)?
skipBytes	How many bytes of the head of the files should be skipped?
verbose	Be verbose?
zeroBased	Do the indices in the file start with 0, e.g. -1 0:2 1:4 ...?

Value

NULL.

Note

Labels can any numeric, they are not converted in any way.

	X = as.matrix(iris[,1:4])
	Y = as.matrix(as.numeric(iris[,5]))
