[R] user input

Dear users,

I have looked on different sources and found different functions to prompt the user to provide input. However, I couldn't find one that does exactly what I'm looking for.

select.list() and menu() are nice because a graphic window appears to prompt the user. However, the user can only choose from a predefined list of choices. readline() and scan() are more free in the input but prompt the user in the console.

Examples:
a <- select.list(choices=c("0.0","0.1","0.2"), title="select number") a ## I cannot choose "0.15"
[1] "0.1"

b <- readline(prompt="select number ")
select number 0.2 ## in the console, not really visible b
[1] "0.2"

I would like both "free" input and a pop-up window. Is there a function for this?

Thanks in advance,
Ivan
