Write Data to a File

Description

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.

Usage

write(x, file = "data",
      ncolumns = if(is.character(x)) 1 else 5,
      append = FALSE)

Arguments

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.
ncolumns the number of columns to write the data in.
append if TRUE the data x is appended to file file.

Examples

# 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))

# the file data now contains the data in x,
# two rows, five cols but the first row is 1 2 3 4 5
write(x)
unlink("data") # tidy up
