Write a Matrix or Data Frame

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

Keywords
file, print
Usage
write.matrix(x, file = "", sep = " ", blocksize)
Arguments
x
matrix or data frame.
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

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

If x is a data frame, the conversion to a matrix may negate the memory saving.

Side Effects

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