[R] readline in function call with space in prompt.

[Karl Ropkins]

Not on a machine with latest R at moment so not ruling out something there, but it is working fine for me.

There *must* be something flaky in your system, but I'm damned if I can
come up with any useful suggestions for tracking down just where that
flakiness lies.  Sorry.

Perhaps try re-installing R???
