Dear R-users, My goal is to construct a levelplot (from the lattice package) with 4 or more individual plots sharing the same colorkey. While this appears to be relatively simple using functions, I haven't been able to find a solution using data matrices. An example of a working levelplot with just one matrix:
d <- replicate(10,rnorm(10)) levelplot(d) I have found partial solutions using print and split to show all 4 levelplots on the same screen, but these would require me to either turn off the colorkey, or show it on every plot. Neither solution is completely satisfactory. If I use the layout-option in levelplot, like so: levelplot(d, layout=c(2,2)) , I get the desired layout, with one large colorkey, main and xlab/ylab, but only one levelplot prints. I have been trying to construct a formula that yields the desired result, but I'm afraid my understanding of data frames, arrays and matrices is not deep enough to do so. If anyone knows of a working solution, I would be very grateful. What I imagine is something along the line of (not working code): d1 <- replicate(10,rnorm(10)) d2 <- replicate(10,rnorm(10)) d3 <- replicate(10,rnorm(10)) d4 <- replicate(10,rnorm(10)) d <- list(d1,d2,d3,d4) di <- c(1,2,3,4) levelplot(x ~ y | di, data = d, layout=c(2,2)) NB! Avoiding the matrices is not an option. Some of them are obtained from raw text files.
