function.Rd currently has no example of "stop", Similarly in Control.Rd, there is currently no example of break: these might be helpful for users.

function.Rd suggestion:
# Often it is useful to be able to exit a function on some condition: Use "stop" to do this testJunk <- function(junk) {

	if( is.null(junk)) {
		stop("Junk must not be null!")



Control.Rd suggestion:

# Example using break: prints n unless n^2 exceeds 9: in which case it exits the loop.

for(n in 1:5) {


   } else {
