[R] using cat()

[[Ricardo Rodriguez] Your XEN ICT Team]

Please, could you give me an example about how to use cat() to read the 
value of a variable in a function? Any other way?

I've found how to make it globally available, thus printing it, but I 
don't know how to read out the value of any variable within the function.

Thanks for your help,

Ricardo
