Re: [R] get current plot dimensions?
par(mfrow) and, apparently layout(), set things up for the next plot but don't change the settings for the current plot. Hence you need to start a new plot to look at the settings for it. If you don't call par(new=TRUE) then the subsequent call to plot() (which calls the equivalent of plot.new()) will start another plot, leaving a hole in the layout.

Re: [R] get current plot dimensions?
Try using the combination plot.new() ; par(new=TRUE) to advance to the next position in the layout before querying par(pin). Be sure to actually plot something after the par(new=TRUE). E.g., layout(matrix(c(1,2,3,4), nrow=2), width=c(1,3), height=c(1,3)) plot.new() ; par(new=TRUE) par(pin) [1] 0.6624667 0.1623834 plot(10:19, main=One) par(pin) [1] 0.6624667 0.1623834 plot.new() ; par(new=TRUE) par(pin) [1] 0.6624667 3.5415500 plot(20:29, main=Two) par(pin) [1] 0.6624667 3.5415500 Bill Dunlap Spotfire, TIBCO Software wdunlap tibco.com -Original Message- From: r-help-boun...@r-project.org [mailto:r-help-boun...@r-project.org] On Behalf Of Not To Miss Sent: Friday, March 08, 2013 5:12 PM To: r-help Subject: [R] get current plot dimensions?
