cat(... , file = "", sep = " ", fill = FALSE, labels = NULL,
append = FALSE)
...
| objects that can be coerced into vectors. |
file
|
character string naming the file to print to. If
"", cat prints to the standard output.
|
sep
| character string to insert between the objects to print. |
fill
|
a logical or numeric controlling how the output is
broken into successive lines. If FALSE, only newlines
created explicitly by \n are printed. Otherwise, the
output is broken into lines with print width equal to the option
width if fill is TRUE, or the value of
fill if this is numeric.
|
labels
|
character vector of labels for the lines printed.
Ignored if fill is FALSE.
|
append
|
if TRUE, output will be appended to
file; otherwise, it will overwrite the contents of
file.

cat converts its arguments to character strings, concatenates
them, separating them by the given sep= string, and then
prints them.
cat is useful for producing output in user defined functions.
