Create conda env file

[sverhoeven]

To install most R dependencies without compiling

[Peter9192]

Phenor and modistools are not available from anaconda channels, so I think we need a separate r-install command anyway. Would this also be an alternative?

# Create a basic conda environment with R and Python
mamba create -c conda-forge -n springtime python=3.9 r-base r-devtools

# Install r-deps from command line (how to make this simpler?)
Rscript -e 'devtools::install_github("bluegreen-labs/phenor")'

# Install python package and verify installation
pip install git+https://github.com/phenology/springtime.git
python -m r2py.situation
> ...
> Calling `R RHOME`: /home/peter/miniconda3/envs/springtime/lib/R
> Environment variable R_LIBS_USER: None
> ...

# Or use hatch
pip install hatch
hatch env create
hatch run python -m rpy2.situation

Can we somehow create an r-package with phenor and modistools as dependencies and make it available on CRAN/conda channels? Or do you want to look at the dependencies from phenor and modistools and see how many of them are available on conda channels already and use that?

[Peter9192]

Perhaps r-essentials already contains the bulk of what we need?

Maybe https://cran.r-project.org/web/packages/packrat/ can be used to make a lock file.
