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

Thanks for your answer. But I don't understand anything, I would say it's far beyond my current knowledge. Could you please explain me in more details how this works?

Hi Ivan, there are also data.entry() and edit(), which are more tailored to data frames and might look awkward for entering a single value. You could also take a look at CRAN, maybe there is a GUI package that does what you want.
