[R] switch of cex adjustment with mfrow?

[S Ellison]

Checking ?par, 
" In a layout with exactly two rows and columns the base value
   of '"cex"' is reduced by a factor of 0.83: if there are three
   or more of either rows or columns, the reduction factor is
   0.66."

You should be able to simply set cex to 1/0.83 for a 2x2 layout and by 1/0.66 for larger layouts, in a nw 'par' call after setting mfrow or mfcol.
More generally, use the cex value set by mfrow/col:

par(mfrow=c(2,2))
par(cex=1/par("cex"))

plot(1:10)
	#Normal size symbols, labels etc.
