On an ubuntu docker image with gdal 3.0.1 and PROJ 6.2.0, I see:
Loading required package: sp
rgdal: version: 1.4-6, (SVN revision (unknown))

but also a warning with sf:

Coordinate Reference System:

Warning message:
In CPL_crs_from_proj4string(x) :
GDAL Message 1: +init=epsg:XXXX syntax is deprecated. It might return
a CRS with a non-EPSG compliant axis order.
so it feels like a combination of how PROJ has been installed, and how
it has been compiled into the R packages.

Dear all,
I am trying to setup R and rgdal within a JupyterLab environment
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 (
I have Python 3.7 and R 3.6 installed, and I'm using "conda" as my
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

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
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,
Is the "+init=epsg" syntax supported with PROJ 6, or should I be using an
alternative?
Thanks and best wishes,
James.
