[R] help using code

[Rui Barradas]

Hello,

I believe you are making a confusion on how to call a function in R. You 
don't replace the argument in the function declaration. what you do is 
to call the function like this:

importdata("~/path to/filename.xyzuvwrgb")

leaving the function definition alone.

Hope this helps,

Rui Barradas
