Lattice plots and missing x-axis labels on second page

I should say I'm using Windows-7, R version 2.13.0 and lattice version

print(xyplot(pdat$NITRATE~pdat$DATEYR|pdat$WELL,
I generally try to avoid building lattice plots this way. It is better to use data=pdat and shorten the formula specification. That way the functions can use the aggregate information in the dataframe. Try: xyplot( NITRATE~ DATEYR| WELL, data=pdat,
as.table=TRUE, layout=c(3,4),
You may want to try layout=c(3,4,2) See help(xyplot) subsection layout, where Sarkar says that pages are somethimes incorrectly calculated.
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.
