| capture.output {utils} | R Documentation |
Evaluates its arguments with the output being returned as a character
string or sent to a file. Related to sink in the same
way that with is related to attach.
capture.output(..., file = NULL, append = FALSE)
... |
Expressions to be evaluated. |
file |
A file name or a connection, or NULL to return
the output as a character vector. If the connection is not open,
it will be opened initially and closed on exit. |
append |
logical. If file a file name or unopened
connection, append or overwrite? |
An attempt is made to write output as far as possible to file
if there is an error in evaluating the expressions, but for file
= NULL all output will be lost.
A character string (if file=NULL), or invisible NULL.
