[R] two panel figure using barplot2

[Adrienne Keller]

I am trying to make a two panel figure using barplot2 in gplots. When  
I use par(mfrow=c(1,2)), two panels are created but both barplots are  
overlaid on top of one another in the first panel and the second panel  
is left blank.  Am I running into problems because I of some  
complexities of gplots? Is there a simple way to make a two panel  
figure with two barplots side by side using barplot2?

Thank you,
