Error: 'rawTransform' is not an exported object from 'namespace:rgdal' in the projectRaster

sessionInfo()

Hi Robert,

I think something happened in the raster package v2.3-33 and your
function projectRaster reports now an error (which probably affects
several other packages).

# create a new (not projected) RasterLayer with cellnumbers as values
r <- raster(xmn=-110, xmx=-90, ymn=40, ymx=60, ncols=40, nrows=40)
r <- setValues(r, 1:ncell(r))
projection(r)

[1] "+proj=longlat +datum=WGS84 +ellps=WGS84 +towgs84=0,0,0"

# proj.4 projection description
newproj <- "+proj=lcc +lat_1=48 +lat_2=33 +lon_0=-100 +ellps=WGS84"

pr1 <- projectRaster(r, crs=newproj)

Error: 'rawTransform' is not an exported object from 'namespace:rgdal'

Thank you!

Hi Tom, your example works for me; maybe update rgdal? If this is the
problem, than raster DESCRIPTION needs to update its rgdal dependency.
