quiet | R Documentation |
This function is used to suppress information printed from external functions
that make internal use of link{message}
and cat
, which
provide information in interactive R sessions. For simulations, the session
is not interactive, and therefore this type of output should be suppressed.
For similar behaviour for suppressing warning messages see
suppressWarnings
, though use this function carefully as some
warnings can be meaningful and unexpected.
