I believe the latter for base R, as the standard contour plotting depends on
internal (fortran, I think) code that works only for rectangular
coordinates.Should be only a few lines of fiddling though (exercise left to


RSiteSearch("polar coordinates", restr="func")  

to see what might be available in packages if fiddling doesn't suit.

Subject: [R] Polar coordinates - contour plots


I have data for contour plot which is given in polar coordinates. Is
there a straightforward way to plot in polar coordinates in R, or do i
need to fiddle with transformations and then to sort the x and y
vectors to be in ascending order as required by contour function and
