[Rd] Interfacing with user in R

[Augusto.Sanabria@ga.gov.au]

Good day everyone,

I am new in R programming (my question may sound
trivial to you): is there any way to ask the user
to enter a string within an R process, say a filename, 
make R to recognise it and open the given file? 
It is a simple exercise in other languages. 
I am using R2.1.1 in a LINUX machine.

Thanks for your help.

Augusto
