I would like to install a local R package into a conda environment. The package is not on CRAN or github (and not on any conda channel). For packages on CRAN this is relatively straightforward:
conda skeleton cran <pckg>
conda-build r-<pckg>
conda install --use-local r-<pcgk>
For packages on github this works similarly: install R package from github using "conda" (apart from some issues of versions requiring tags).
conda skeleton cran <url>/<pcgk>
conda-build r-<pckg>
conda install --use-local r-<pcgk>
However, I cannot get this to work with a local package (the package builds without problems using R CMD build). This is what I have tried:
conda skeleton cran <path>/<pcgk>
Connects to cran and then (of course) does not find the package.
conda skeleton cran --cran-url <relative_path>/<pckg> <pckg>
throws an error with:
requests.exceptions.MissingSchema: Invalid URL '<relative_path>/<pckg>/src/contrib/': No schema supplied. Perhaps you meant http://<relative_path>/<pckg>/src/contrib/?
conda skeleton cran <absolute_path>/<pckg> <pckg>
Throws:
File "/home/myuser/.conda/envs/myenv/lib/python3.9/site-packages/conda_build/skeletons/cran.py", line 743, in package_to_inputs_dict
pkg_name = re.match(r'(.*)_(.*)', pkg_filename).group(1).lower()
AttributeError: 'NoneType' object has no attribute 'group'
And lastly:
conda skeleton cran --cran-url <absolute_path>/<pckg> <pckg>
Throws:
File "/home/myuser/.conda/envs/myenv/lib/python3.9/site-packages/requests/sessions.py", line 742, in get_adapter
raise InvalidSchema("No connection adapters were found for {!r}".format(url))
requests.exceptions.InvalidSchema: No connection adapters were found for '<absolute path>/<pckg>/src/contrib/'
Is this not possible with conda? Or am I making a mistake?
Here someone tried to write the skeleton files for a local package themselves, but it seems without success.
