[R] multiple boxplots

[J.M. Breiwick]

Hello,

I want to plot 3 boxplots [ par(mfrow=c(3,1)) ] but the first one has 8 
groups, the 2nd has 7 and the third has 6. But I the groups to line up:

 1 2 3 4 5 6 7 8
   2 3 4 5 6 7 8
      3 4 5 6 7 8

where the numbers actually refer to years. I suspect I have to manipulate 
the function bxp(). Is there a relatively simple way to do this? Thanks for 
any help.
