I am trying to upload several rasters on tif format with google-collaboration. However I always had the same error message:
"Cannot create RasterLayer object from this file; perhaps you need to install rgdal first"
So, I tried to install rgdal...and another error appeared:
"Installation of package had non-zero exit status."
I tried to install using a local file, and apparently, its run ok, however, when i required the package, another error appeared:
"Error in library(rgdal) : there is no package called ‘rgdal’
/usr/local/lib/python3.6/dist-packages/rpy2/rinterface/init.py:146: RRuntimeWarning: 4: warnings.warn(x, RRuntimeWarning) /usr/local/lib/python3.6/dist-packages/rpy2/rinterface/init.py:146: RRuntimeWarning: 5: warnings.warn(x, RRuntimeWarning) /usr/local/lib/python3.6/dist-packages/rpy2/rinterface/init.py:146: RRuntimeWarning: 6: package ‘rgdal’ is not available (for R version 3.6.1)"
Could anyone help me to fix these errors?
I provide my session info and a fragment of code
