[R-sig-Geo] create cartogram shape files in R

[Jose M. Pavia]

Dear list,

I have a shape file (~6000 polygons). The areas of the polygons in 
the shape file are really different, despite having be all of them 
designed to have similar population sizes. To perform posterior 
analyses using wavelets, I am interested in transforming these shape 
file in a cartogram shape file with (almost) equal density population 
in all of the resulting polygons. I wonder if somebody knows how we 
can solve this in R? Can anybody help?

best regards
jm
