timeout (Package: memoise) : Return a new number after a given number of seconds

This function will return a number corresponding to the system time and remain stable until a given number of seconds have elapsed, after which it will update to the current time. This makes it useful as a way to timeout and invalidate a memoised cache after a certain period of time.

memoise (Package: memoise) : Memoise a function.

mf <- memoise(f) creates mf, a memoised copy of f. A memoised copy is basically a lazier version of the same function: it saves the answers of new invocations, and re-uses the answers of old ones. Under the right circumstances, this can provide a very nice speedup indeed.
