If I define this function
R> ask <- function (message = "Type in datum")
eval(parse(prompt = paste(message, ": ", sep = "")))
the following is produced as expected on a Linux/debian machine
R> ask("input")
input: 3
[1] 3
R> ask("input")
input: 3:6
[1] 3 4 5 6
R> ask("input")
input: c(3,6)
[1] 3 6
If I run exactly the same on a Mac (OS X 10.5.6), it still works
provided R is run in a Terminal window.
The outcome changes if R is run in "its own window", started by clicking
on its icon; the first two examples are still Ok, the third one produces:
*** caught segfault ***
