Hi Mark,
I believe the argument you are looking for is column not ncol.
Try the following:
library(lattice)
xyplot(1~1,
auto.key=list(
bty='n',
pch=rep(c(15,17),2),
col=c('brown','green','blue','red'),
columns=4,
text=c('How','to make','this into', 'a grob?'),
space="top"
))
Regards
Markus

Subject: [R] Creating a flat legend 'grob' for lattice xyplot
Hi,
I want my xyplot legend to be flat, not tall, and there seems to be no way for
xyplot's auto.key and key elements to do this: I tried many, many permutations
of what I could find in the archives and reading the documentation. If there
there's a way to make it flat, please tell me what the magic incantation is.
Here's a simple example of what I like to see. The xyplot will be a
multi-panelled one with a single, flat legend below. It seems the xyplot's
legend element is the way to go -- the option I haven't tried because I don't
know what or how to create a grob of this kind. Where to start?
xyplot(1~1)
legend(0.15,-0.125,
bty='n',pch=rep(c(15,17),2),col=c('brown','green','blue','red'),ncol=4,
legend=c('How','to make','this into', 'a grob?'))
Thanks!
