[R] Arrange histogram

[Jue.Wang2 at sanofi-aventis.com]

The data set has a number of variables each of which is classified into two groups.

For each variable of each group, I need to create a histogram. All the histograms are to be lined up into a file that looks like

               group1         group2
Variable 1     Histogram      histogram
Variable 2     Histogram      histogram
...........................

Can you give me a hint as to what package I'd look into for help?

Thank you
