[R] Lattice plots and missing x-axis labels on second page

[Evans, David G (DFG)]

I should say I'm using Windows-7, R version 2.13.0 and lattice version
0.19-33.  I've pared down my code to this :

pdat = read.table("RGRAPHSDGE.csv",header=T,sep=",",fill=T)
print(xyplot(pdat$NITRATE~pdat$DATEYR|pdat$WELL,
as.table=TRUE,
layout=c(3,4),
xlab="Year",
ylab="Nitrate mg / litre",
strip=FALSE
)) 

First 3 lines of pdat looks like this:
                      WELL   DATEYR NITRATE
1 ALASKA CHILDRENS SERVICES 1993.836    0.81
2 ALASKA CHILDRENS SERVICES 1994.850    0.91
3 ALASKA CHILDRENS SERVICES 1995.803    0.94
....
Thanks again.

Subject: [R] Lattice plots and missing x-axis labels on second page

Hello,
I'm trying to make a lattice plot (using xyplot()). I have included a
"layout=c(3,4)" statement, giving me 12 plots per page and an
"as.table=TRUE" statement, directing the way the plots are laid out.  I
have 18 plots altogether and so 6 of them end up on the second page.
Everything looks fine for the first page, but the x-axis labels (e.g.
1993, 1994...) are all missing on the second page.  The x-axis variable
name ("Year") is there at the bottom, however.   Any help is
appreciated. Thanks.
