Suppress function messages and Concatenate and Print (cat)

Description

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 behavior for suppressing warning messages see suppressWarnings, though use this function carefully as some warnings can be meaningful and unexpected.

Usage

quiet(..., messages = FALSE, cat = FALSE)

Arguments

`...`	the functional expression to be evaluated
`messages`	logical; suppress all messages?
`cat`	logical; suppress all concatenate and print calls from `cat`?

Examples

myfun <- function(x){
   message('This function is rather chatty')
   cat("It even prints in different output forms!\n")
   message('And even at different....')
   cat("...times!\n")
   x
}

out <- myfun(1)
