ibreak {itertools} | R Documentation |
Create an iterator that iterates over another iterator until
a specified function returns FALSE
.
This can be useful for breaking out of a foreach loop, for example.
ibreak(iterable, finished)
iterable |
Iterable to iterate over. |
finished |
Function that returns a logical value. The iterator
stops when this function returns |
# See how high we can count in a tenth of a second
mkfinished <- function(time) {
starttime <- proc.time()[3]
function() proc.time()[3] > starttime + time
}
length(as.list(ibreak(icount(), mkfinished(0.1))))
