[R] Display variables when running a script

[naw3 at duke.edu]

Hi,

I know this must be a stupid question, and sorry in advance for being such a
noob. But, is there way to get R to display only certain variables when running
a script. I know if you want to see the value of a variable when using the
interface, you just type it in and hit enter, but is there a command that I can
use in a script file that will show the value at a certain point?

Thanks,
