> I want to get a image of plot(a,b) and plot(c,d).What happens when you type the above without "trellis.device(...)" and "dev.off()". Does that look like the plot you wrote to file? R is one of those funny software tools that does what you tell it. 1) "plot()" isn't a lattice function, so using the function "bmp(file = "test.bmp", bg = "white")" instead of "trellis.device()" is safer. 2) you haven't told R that you want two plots on one page, nor how you want to arrange them. See ?layout and ?par. On the par help page, pay careful attention to the mfcol and mfrow arguments. 3) type "help.start()", and follow the link to "An Introduction to R", particularly the graphics section. Then play with this. par(mfcol=c(2,1)) plot(a,b) plot(c,d) Have fun!
