  Dear all,

I'd like to know how I could compute the parameters "yaxp" and (the y 
components of) "usr" without having to plot the data first. Note that 
"ylim" is /a priori/ fixed.

The aim is to automatically adjust the parameter "mgp" without having to 
make the plot twice. Then, with "yaxp" and "usr" known, it should be 
easy to calculate a suitable "mgp" with the axTicks and strwidth functions.

Many thanks in advance,
Yves
