write.matrix 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)
Arguments
x |
matrix or data frame. |
file |
name of output file. The default ( |
sep |
The separator between columns. |
blocksize |
If supplied and positive, the output is written in blocks of |
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.
