Dear R-help, I have a matrix of data values specified in polar coordinates, i.e. (r,theta).
I know that I can transform this image to Cartesian coordinates and then use image to display the results, however, I want to display the image as is, without any coordinate transformations. This would require displaying individual "pieces of pie" colour-coded by their data value. A comparable plotting routine in Matlab would be pcolor (which doesn't require a regular grid) or the use of polyfill in IDL to fill each polygon. Does anyone know of a package that could help me out? Any help appreciated.
