Dear all,
I've found this nice code fragment on the web
(from Jan T. Kim if I'm correct):
hitReturn <- function(msg)
{
invisible(readline(sprintf("%s -- hit return", msg)));
}
But it does not seem to work in non-interactive mode
( I mean, when I start a script like this: R --vanilla < script.R )
It simply continues, I guess the stdin is not connected?
Does somebody know how to make it work.
My script plots a few graphs (in X11 windows) and I don't want them to
disappear immediately.
A Sys.sleep(infinite) would probably work, but I thought there might
be a better solution?
Thanks,
Jonne.
