[R] scientific vs. fixed notation in xyplot()

[Don McKenzie]

This is quite elegant (thanks) and brings up a problem I could not  
solve awhile back, although Dr. Sarkar did his best to help.
How do I do the same thing in a panel plot?

e.g., toy example

temp.df <- data.frame(X=seq(1,100,by=1),Y=seq(1,50.5,by=.5),class=rep 
(c("A","B"),each=50))
xyplot(Y ~ X | class,data=temp.df,scales=list(x=round(log(1:100),  
4),y=round(log(1:50.5), 4),log=T))

gives me the right points on the page but still gives axis labels in  
scientific notation.

If I try to specify "labels" as a list I get an error message

 > xyplot(Y ~ X | class,data=temp.df,scales=list(log = T, labels =  
list(x=round(log(1:100), 4),y=round(log(1:50.5), 4))))

Error in construct.scales(log = TRUE, labels = list(x = c(0, 0.6931,  
1.0986,  :
   the at and labels components of scales may not be lists when  
relation = same

Syntax problem in this last command?

Thanks
