par(uin)

Hi,

I've been trying to use several plotting routings that make use of
S's par("uin"), the number of user units per inch.  For the moment I've
substituted all of the occurences of this with

   par.uin _ function() 
       (par("fin") / c( diff(par("xaxp")[1:2]),diff(par("yaxp")[1:2])))

This seems to work fine for my needs.
