Hi,
Can someone of you tell me why these two simple examples works as
"expected",
plot(c(1,1,2,2)~c(1,2,1,2),col=c(1,2,3,4),pch=c(1,2,3,4))
coplot(c(1,1,2,2)~c(1,2,1,2)|c("A","A","B","B"),col=c(1,2,3,4),pch=c(1,2,3,4
))
but when I try it with xyplot in the lattice package it fails.
xyplot(c(1,1,2,2)~c(1,2,1,2)|c("A","A","B","B"),col=c(1,2,3,4),pch=c(1,2,3,4
))
Do I have to specify colors and symbol types differently with lattice
functions or
is this a bug?
Thanks,

Both panels should use pch 1 and 2 (and not 3 and 4 for the second panel like coplot), which seems reasonable enough; it starts afresh for each panel. The col isn't vectorized because grid doesn't support vectorized graphical parameters yet (but will do so from the next version). That said, from a design perspective, col and pch should not be vectors at all in your example. S-Plus would actually ignore vectorized col/pch etc (with a warning) and use only the first values. Multiple graphical symbols are supposed to be achieved via the groups argument and panel.superpose.

Your xyplot(...) command works fine for me. Are you sure the lattice library
is correctly loaded, using:
library(lattice)
Also, what is your plateform and your R /lattice / grid versions? Mine are:
_
platform i386-pc-mingw32
arch i386
os mingw32
system i386, mingw32
status
major 1
minor 5.1
year 2002
month 06
day 17
language R
under Windows 2000 pro, and:
Package: lattice
Version: 0.5-3
Date: 2002/05/30
Package: grid
Version: 0.6
