[R] Bug or feature in xyplot?

[Philippe Grosjean]

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
Date: 2002/04/03

Best,

Philippe Grosjean

Objet : [R] Bug or feature in xyplot?


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,
