plot a subset of intervals after lmList

Dear reader,

I am a first timer here (and an R newbie), so please tell me if you need more information to answer the following question:

I have grouped data on insurance premiums for 7 companies. I estimated 7 individual linear models using lmList of the nlme library. Afterwards I can plot the intervals of all parameter estimates neatly using plot(intervals(lmListObject)). However, as I have 40 covariates this command results in 40 plots cramped together into one plot, which is impossible to read.

Q: Is there a way to make 4 plots each consisting of the interval plots of 10 covariates?

Many thanks in advance,
Dirk Sackman
