[R-sig-Geo] R function checking/transforming CRS layer R function

[dave]

If your original data is not in the desired projection, changing the CRS
attributes will not do the transformation for you.  In the case of vector
data, you will need to use spTransform().  For raster data, you might be
able to use projectRaster() but I would recommend using gdalwarp().

I wrote a brief blog post about this question, here:
