Thank, Deepayan Sarkar and Sundar Dorai-Raj for their quick responses. After
updating lattice, the problem resolved.

Subject: [R] Lattice bwplot error
Dear all;
Searching the R site for answers to my problem, but found none.
Here is the run and error:
bwplot(dev ~ Dbhcl | Period, data = DbhValid2, font = 2,
+ main=list(" "), axis.font =2,
+ ylab = list(label = "Residual (cm)", font = 2),
+ xlab = list(label = "Dbh class (cm)", font = 2),
+ par.strip.text=list(cex=0.8, font=2),
+ panel=function(x, y) {
+ panel.grid()
+ panel.abline(h = 0)
+ panel.bwplot(x, y, horizontal = TRUE)
+ }
+ )
Error in "[<-"(`*tmp*`, pos.heights[[nm]], value = numeric(0)) :
nothing to replace with
str(DbhValid2$dev)
num [1:11469] 0.318 0.764 1.230 0.403 0.526 ...
str(DbhValid2$Dbhcl)
Factor w/ 26 levels "2","3","4","5",..: 9 9 9 10 10 10 10 11 11 11 ...
Stepped through debugging bwplot(), I couldn't locate where the error
occurred (there are more than 11,000 data points). However, I had no problem
using boxplot() to generate four graphs separately:
Any ideas and suggestions?
TIA,
