Dear R-help,

I'm using 63.3 on windows NT. The improved graphics device has  a problem
in that the default par settings produce text that is way too small (63.2
seemed fine). I've compared the parameters between 63.3 and 63.2 and the
ones that differ are : cin, cra, csi, mai, pin, plt. In the par help file,
cin and cra have no documentation other than that they are read only, the
last three don't appear to concern text size. The all important one is csi,
the height of default characters in inches, in 63.2 it is 0.2755906, in
63.3 it's 
0.1377953, unfortunately it is also read only. I suppose in theory this can
solved using cex, but that alters everything, and in a scatterplot, say,
you get circles that look rather too big, and it generally contravenes the
'flexibility is paramount' philosophy of R/S+. I guess what I'm asking is
how do you get around the read only problem, or what's an alternative?  

Incidently, the 63.3 doesn't have the lty problem with lines(), as was
