[R] 3 levelplots and 1 colorbar

[Joaquin Rapela]

I want to create a simple plot containing three levelplots with one colorbar.
I used the "Three levelplots" code below, but the third levelplot is drawn
smaller than the first two. However, if I try the "Two levelplots" code below
it works well. Can anybody tell me how could I draw three levelplots (of the
same size) with one colorbar.

Thanks in advance, Joaquin

### Three levelplots ###
frame <- matrix(rnorm(16*48), nrow=16)

p <-levelplot(frame, colorkey=FALSE)
print(p, position=c(0,0,1/3,1), more=TRUE)
p <-levelplot(frame, colorkey=FALSE)
print(p, position=c(1/3,0,2/3,1), more=TRUE)
p <-levelplot(frame, colorkey=TRUE)
print(p, position=c(2/3,0,3/3,1), more=FALSE)

### Two levelplots ###

frame <- matrix(rnorm(16*48), nrow=16)

p <-levelplot(frame, colorkey=FALSE)
plot(p, position=c(0,0,1/2,1), more=TRUE)
p <-levelplot(frame, colorkey=TRUE)
plot(p, position=c(1/2,0,1,1), more=FALSE)
