Dear all, I am trying to setup R and rgdal within a JupyterLab environment alongside my usual Python tools. I realise this is probably an unfamiliar setup for many, but I hope someone might be able to help nevertheless.
I'm using a Docker container based on Ubuntu 18.04 and derived from the Jupyter Data Science Notebook ( https://github.com/jupyter/docker-stacks/tree/master/datascience-notebook). I have Python 3.7 and R 3.6 installed, and I'm using "conda" as my package manager. I have successfully installed GDAL and PROJ, together with various Python and R packages, including 'sp' and 'rgdal'. When I run require(rgdal) I see the following Loading required package: rgdal Loading required package: sp rgdal: version: 1.4-4, (SVN revision 833) Geospatial Data Abstraction Library extensions to R successfully loaded Loaded GDAL runtime: GDAL 2.4.2, released 2019/06/28 Path to GDAL shared files: /opt/conda/share/gdal GDAL binary built with GEOS: TRUE Loaded PROJ.4 runtime: Rel. 6.1.0, May 15th, 2019, [PJ_VERSION: 610] Path to PROJ.4 shared files: (autodetected) Linking to sp version: 1.3-1 which seems OK. Most things work as expected, but this CRS("+init=epsg:3035") gives an exception Error in CRS("+init=epsg:3035"): no arguments in initialization list The same code works fine in R-Studio, although I note that my R-Studio installation has PROJ 4.9.2 (with the same versions of rgdal and sp as listed above). Unfortunately I can't downgrade PROJ, since some of my Python packages require version 6.1. I have read that rgdal is compatible with PROJ6 and I haven't been able to find (m)any similar issues online, so I assume I'm doing something wrong. As a workaround, this runs successfully showP4(showWKT("+init=epsg:3035")) But the original syntax is cleaner and I'd rather not refactor all my old code if I can help it. Can anyone point me in the right direction, please? Is the "+init=epsg" syntax supported with PROJ 6, or should I be using an alternative? Thanks and best wishes, James.
