[R-sig-Geo] problem in weigths of the extract function

Dear list,

I recently upgraded the "raster" library and a script that used to run
perfectly gave me some mistakes. The problem was in the extract function:

r <- raster(nrows=180, ncols=360, xmn=-180, xmx=180, ymn=-90, ymx=90)
r[] <- 1
extract(x = r, y = world_map, weights=T, cellnumber=T)

I've tried different combinations of rasters and polygons and there were
mistakes with the weights output.

The solution I figured was to downgrade the package to the previous version
I was using (2.1-49), and everything is working again

Just thought this was something to share...

Best,
Daniel
