...ALSE) I want to get rid of the space (margins) around the longest axis for each variety of levelplot. So I tried to capture the viewport height and width and print the levelplot within a region which reflects the aspect ratio of the plot. I run into an error message as below: width.vp <- convertWidth(grobWidth(grid.rect()), 'cm') height.vp <- convertWidth(grobHeight(grid.rect()), 'cm') width.vp;height.vp # this works if(asp.ratio.1 < 1) {height.vp <- unit(as.numeric(height.vp)*asp.ratio.1, "cm")} if(asp.ratio.1 > 1) {width.vp <- unit(as.numeric(width....

Hello! I first would like to compliment the authors of grid on what has been a wonderfully useful package for me. Now, my question: Is there any way I can specify the size of some grid.text using grid units? I must label the regions of a plot. The regions can be either very small or very large, so I would like to label each by fitting its text to the size of the region in question. Ideally, I
