Hello,
A few questions about the following examples:
1. Why do the two plotting versions not produce the same result?
2. Is the 'scale_x_continuous' (or *_y_* or *_*_discrete) geom the best
way to setup grids (as in visual guide-lines) in polar (or for that
matter, any) coordinate system?
3. Why
Yes! Again, thank you ALL very, very much.
Even simply lurking on the list generates many gems worth collecting.

I have a set of one-liners (many thanks to previous responses from this
