I was hoping that the following specification postscript(file="fig.ps",height=2,width=4) par(mar=c(5,5,2,2)+.1,mfrow=c(1,2),mex=.6) would yield the same scaling effect as postscript(file="fig.ps",height=2,width=6) par(mar=c(5,5,2,2)+.1,mfrow=c(1,3),mex=.6) but the fact is that the 'mfrow=c(1,2)' yields smaller plotting frame and bigger font size.

Is there a way to adjust the font size for axis labels when using persp()? The parameter cex works for adjusting the global font size, but I can't seem to make cex.lab or cex.axis work for adjusting these values independently. Or, is there a preferred method for making surface plots in R? I'm using R version 1.8. Thanks, Manuel

Hi all, In R, it is not possible to set the font size of axis labels directly (AFAIK). Instead, scaling factors for the font chosen by the graphics device can be supplied. It appears that there is no constant font size for axis labels. My impression is that the axis label font size is scaled internally by R depending on the number of labels given for an axis. In addition to the R-internal
