[R] changes to y-axis labels in lmList intervals plot

[William Dieterich]

Dear List,

I am plotting lmList objects using plot(intervals()) in nlme 
package.  I want to make changes to the y-axis labels. When I 
try to change cex of y-axis labels using the following: 

fm1 <- lmList(distance ~ age | Subject, Orthodont)
plot(intervals(fm1), scales=list(y=list(cex = .7)))

I receive: Error in bwplot(formula = group ~ intervals | what, 
data = structure(list( : formal argument "scales" matched by 
multiple actual arguments

I have searched the documentation on Trellis and Lattice but 
can't seem to figure this out.

Any help would be greatly appreciated.

Thank you,

Bill Dieterich
