I apologize, I thought my example was fairly self-contained.


I am attaching a sample data table (a subset). This is the code:

library(nlme)
library(lattice)
 tst <- read.table("sil.txt",header=TRUE)
 mydatausegroup <- groupedData( BF ~ HO  | ID/Infa/Day, data=tst)
 plot(na.omit(mydatausegroup), displayLevel=2,layout=c(10,2),aspect=2)
> min(mydatausegroup$Day)
[1] 8
> min(mydatausegroup$Day)
[1] 1


Note that layout is too large now, but that does not matter.

Thanks,

Turgut
