[R-sig-Geo] Error in CRS("EPSG:4326") : no arguments in initialization list

[Tomislav Hengl]

Thanks Roger. If I understand correctly, I should simply replace 
'CRS("EPSG:4326")' with 'CRS("+proj=longlat +datum=WGS84 +no_defs")'. 
Otherwise the EPSG codes should work in R with any version correct?
