[Yang, Richard]

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:

> boxplot(dev ~ Dbhcl, data=DbhValid2[DbhValid2$period == 5,])

Any ideas and suggestions?

TIA,

Richard Yang
