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
