Having an error in getting library raster to read data from a netcdf file when reprojecting a raster. I'd appreciate any workarounds you can suggest.

projectRaster error with netcdf

The second argument in projectRaster is another Raster* object, not a proj.4 string. I expect this problem goes away if you do: x <- projectRaster(r, crs="+proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs") Robert
