[R] Bug or feature in xyplot?

[Hans Gardfjell]

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,
