| write {base} | R Documentation |
The data (usually a matrix) x are written to file file.
If x is a two-dimensional matrix you need to transpose it to get the
columns in file the same as those in the internal representation.
write(x, file = "data",
ncolumns = if(is.character(x)) 1 else 5,
append = FALSE, sep = " ")
x |
the data to be written out. |
file |
A connection, or a character string naming the file to write to.
If "", print to the standard output connection.
If it is "|cmd", the output is piped to the command given
by ‘cmd’.
|
ncolumns |
the number of columns to write the data in. |
append |
if TRUE the data x is appended to file file. |
sep |
a string used to separate columns. Using sep = "\t"
gives tab delimited output; default is " ". |

save for writing any R objects,
write.table for data frames,
and scan for reading data.
# create a 2 by 5 matrix
x <- matrix(1:10,ncol=5)
# the file data contains x, two rows, five cols
# 1 3 5 6 9 will form the first row
write(t(x))
# Writing to the "console" 'tab-delimited'
# two rows, five cols but the first row is 1 2 3 4 5
write(x, "", sep = "\t")
