| write.matrix {MASS} | R Documentation |
Writes a matrix or data frame to a file or the console, using column labels and a layout respecting columns.
write.matrix(x, file = "", sep = " ", blocksize)
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.
|
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.
A formatted file is produced, with column headings (if x has them)
and columns of data.
