Thanks Peters!
Just a few minor glitches now:
require(lattice)
data<- data.frame(SP=sort(rep(as.factor(c('A','B','C','D','E')),12)),
x=rpois(60,10),
y=rep(c(rep(0,4),rep(10,4),rep(20,4)),5),
z=rep(1:4,15))
xyplot(x~y|SP,data=data,groups=z,layout=c(2,3),pch=1:4,lty=1:4,col='black',type='b',
key=list(x = .65, y = .75, corner = c(0, 0), points=TRUE,
lines=TRUE, pch=1:4, lty=1:4, type='b',
text=list(lab = as.character(unique(data$z)))))
I have an extra column of symbols on the legend,
and,
would like to add a title to the legend. Such as 'main' for plots.
Any suggestions?
for key(), make 'lines' into a list:
xyplot(x~y|SP,data=data,groups=z,layout=c(2,3),
pch=1:4,lty=1:4,col='black',type='b',
key=list(x = .65, y = .75, corner = c(0, 0),
title="title here", cex.title=.9, lines.title=3,
lines=list(pch=1:4, lty=1:4, type='b'),
text=list(lab = as.character(unique(data$z)))))

How do I put a legend for the grouping variable in the
empty upper-right panel?
See the help page for xyplot for an example using the iris data.
You just need to add something like
auto.key = list(x = .6, y = .7, corner = c(0, 0))
to your lattice call. See the 'key' entry on the ?xyplot page.
