Which is a mess! We also have
So wouldn't it be more obvious to use
(and set it with X11.options(pointsize=12))?
If we go to 10pt default, we also need to discuss the multiframe
scaling issue. The current rules are that if there is two rows and/or
columns, reduce font size to 80%, if there are three or more reduce to
50% and a 5pt font @100dpi is a tad small. Note that this rule is
*device independent*, so one would have to check that it still looks
reasonable on postscript and windows. I think it works out OK if one sets the
rule to 60% giving a 6pt font, but I'd like someone elses eyes on

Hmm. I'm not so sure we're really gaining much from an elaborate
par.default() function. If one desires, one could do it via the
startup function, simply by a call to par based on the options).
For instance, try changing X11 to
X11<-function (display = "", width = 7, height = 7, pointsize = 12,
gamma = 1, colortype = options()$X11colortype, maxcubesize = 256)
.Internal(X11(display, width, height, pointsize, gamma, colortype,
