See the recent discussion about changing the line _type_
in radial.plot() where I gave suggestions to change two
lines in radial.plot(). Change the same two lines by adding
'lwd = grid.lwd' to each and adding the argument
'grid.lwd = 1' to the function arguments. Save
the edited function as 'myradial.plot', say. Then
edit the function polar.plot by replacing the single
instance of 'radial.plot' with 'myradial.plot' and
save the edited version as 'mypolar.plot', say. Now
use mypolar.plot() with whatever grid.lwd value suits
your purpose.
