Matthieu, A couple of points that you may be misunderstanding:
1. your 'mar' setting overwrites the 'mai' setting; use one or the other. 2. pdf(width=0.5, height=0.3) sets the *device* region dimensions, not the *plot* region. The thing to remember is that "device contains figure contains plot". [check par()$din, par()$fin, par()$pin] You're fitting a plot plus margins plus outer margins into a device; unless all margins are zero, the plot will have to be smaller than the device region. Note also that your 'mai' setting interacts with the 'pin' setting. Try this on your monitor: par(mai = rep(.1,4), pin = c(0.5, 0.3)) plot(1:10) dev.off() par(pin = c(0.5, 0.3), mai = rep(.1,4)) plot(1:10) dev.off() There's a note on the ?par page: "In particular, the settings of mai, mar, pin, plt and pty interact, ..."

Dear R List Could I ask again my question about where the size of a plot should be specified (in par or pdf?). I still did not figure out, and any help would be much appreciated!! Thanks a lot!

Since I will export it, I use also pdf(). The plot works fine, but once I specify the size in pdf() I get problems... see: Say I specify my plot as following: par(pin=c(0.5, 0.3),mai=rep(0.1,4), omi=rep(0.01,4), mar=c(5,4,4,2)) plot(runif(100)) If I now add pdf() par(pin=c(0.5, 0.3),mai=rep(0.1,4), omi=rep(0.01,4), mar=c(5,4,4,2)) plot(runif(100)) dev.off() The resulting pdf has not the size specified! If I specifz this size in pdf(), I get an error... pdf("try.pdf", height=0.3, width=0.5) par(pin=c(0.5, 0.3),mai=rep(0.1,4), omi=rep(0.01,4), mar=c(5,4,4,2)) plot(runif(100)) Error in plot.new() : figure margins too large So obviously pdf() is modifying some other par() parameter I could not figure out... Any idea? Thanks!!
