Bug or misunderstanding of par(pin)?
Hi Vera, You need to do it in two steps, I think because the different parameters you're trying to set interact. par(mfrow=c(3,4),mai=c(0.04,0.04,0.04,0.04), omi=c(0.2,0.32,0.32,2.16)) par(pin=c(1,0.87)) for(i in 1:12) plot(1:10, 1:10) For this level of control, you probably also want to explicitly set the dimensions of your device; see the help for whatever one you're using for more information.

Dear all, I am currently trying to create a plot showing multiple single plots, for which the important issue is that the size of each plot region (not figure region!) has to be of a fixed dimension (in my case: width=1 inch, height= 0.87 inches). I tried to use "pin" to fix the plotting region to a specific size, but without success. The following example will visualize the problem: par(mfrow=c(3,4),pin=c(1,0.87),mai=c(0.04,0.04,0.04,0.04), omi=c(0.2,0.32,0.32,2.16)) plot(1:10,1:10) plot(10:20,10:20) plot(20:30,20:30) plot(30:40,30:40) plot(2:11,2:11) plot(11:21,11:21) plot(21:31,21:31) plot(31:41,31:41) plot(3:12,3:12) plot(12:22,12:22) plot(22:32,22:32) plot(32:42,32:42) --> You can see that the single plots are higher than wide and not reflecting the size pin=c(1,0.87). The same if you set pin to c(1,1)... you will not get a plotting region of the size 1 * 1 inch. (Don't worry about the large white space on the right hand side or the fact that the labels are printed on top of another figure, this is all easily solvable) The question is, do I misunderstand the use of "pin" or is there a bug? And equally important, does anybody know how I could get this type of plot in an easy way? Thank you very much, Vera PS: in case it is not clear what I mean with "plotting region", please check page 6 of the following document http://www.stat.auckland.ac.nz/~paul/Talks/Rgraphics.pdf
