[R-sig-Geo] any way to prompt users for information?

[Denis Chabot]

Dear R users,

I am trying to automate some analyses for people who will know very  
little about R. At some point in the program, I'd like to ask the  
user to answer a question so that the program can take action  
according to the answer given. Just making a question appear in the  
console is not ideal, it is easily missed by users who will be  
watching mostly for figures I'll produce.

I am hoping there is a way to make a simple text window pop up with  
my question in it, and the cursor placed ready for the user to type  
his answer.

I already made it easy for the user to chose which file to analyse  
with the command

txt <- file.choose()

I tried to look into the help system and found nothing, although I  
may be using the wrong keywords to get something out of the help  
system or of RSiteSearch.

I'd appreciate being put on the right track!

Thanks in advance,

Denis Chabot
