Write a Matrix or Data Frame

DESCRIPTION:

Writes a matrix or data frame to a file or the console, using column labels and a layout respecting columns.

USAGE:

write.matrix(x, file="", sep=" ", blocksize)

REQUIRED ARGUMENTS:

x
matrix or data frame.

OPTIONAL ARGUMENTS:

file
name of output file. The default ( "") is the console.
sep
The separator between columns.
blocksize
If supplied and positive, the output is written in blocks of blocksize rows. Choose as large as possible consistent with the amount of memory available.

DETAILS:

Supplying blocksize is more memory-efficient and enables larger matrices to be written, but each block of rows might be formatted slightly differently.

SIDE EFFECTS:

A formatted file is produced, with column headings (if x has them) and columns of data.
