Thanks, Deepayan.
Is it at least possible to increase the space between the panels in the following plot?:
library(lattice)
x=rep(c(1,2,3),4) # x values
y=1:12 # y values
z=rep(1:4,each=3) # panel number
xyplot(y~x|z,type="l",aspect=1,layout=c(2,2),
scales=list(relation="free",alternating=c(1,1),tck=c(1,0)),
panel=function(...){
panel.xyplot(...,col=1)
}
)
