Thanks Bert for the answer! I'll try to find an appropriate package. In the end, i have "fiddling".
But, can anyone tell me, were I to create an underlying implementation of cooridnate transforms, perhaps controlled by user via 'par', would I need to change the handling of e.g x,y data by every different high-level plot? Or, are there some general, overridable, methods the plotting functions call in order to create plotting points from data?
