Re: [R] Set size of plot: in pdf() or par() ?

Re: [R] Set size of plot: in pdf() or par() ?
It should be specified in pdf() as you did. If you try pdf(try.pdf, height=2, width=2) 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() I think the problem will become apparent. best, Ista On Wed, Feb 23, 2011 at 12:39 PM, Matthieu Stigler matthieu.stig...@gmail.com wrote: Dear R List Could I ask again my question about where the size of a plot should be specified (in par or pdf?).

Re: [R] Set size of plot: in pdf() or par() ?
Dear Ista Thanks a lot for your help!

Re: [R] Set size of plot: in pdf() or par() ?
Thanks Mark! But how does the resulting plot look like on your machine? For me, it is terrible... I tried then removing the mai par (to 0.01), and then got huge circles... It looks like there are many more parameters, I changed then cex, got better but still many adjustments... seems a nightmare! pdf(paper=special, file=try.pdf, height=0.3, width=0.5) par(pin=c(0.5, 0.3), mai=rep(0.05,4), omi=rep(0.01,4)) plot(runif(100), cex=0.005) dev.off() Or am I missing one important parameter that would resize the whole thing? I guess the best workaround is just to specify a rectangular plot keeping values close to the usual ones, and then resize later one, as suggested by David (but could not find the thread mentioned).

Re: [R] Set size of plot: in pdf() or par() ?
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, ...
