[GRASS-user] calculating maximum and minimum diameters with GRASS or R and GRASS?

Hi,

I have 900 polygons and I need to calculate their maximum and minimum
diameters I have GRASS and R and MySQL on Ubuntu, although my R skills are
still developing. I really do not want to measure each one by hand as I do
not have the time! I have managed easily to calculate perimeter and area,
anyone know how to do this?

thanks

Gary
