Using R packages (installed with conda)

My streamlit application runs a set of subprocess calls to R. Hence, I need to use conda to install some of the requirements. Is there a way to do this? Is a docker container the only approach, or can I have conda as a requirement and then use it to install the R packages?

I managed to create a docker solution. Here’s the docker script I ended up with:

FROM continuumio/miniconda3


# Create the environment:
COPY ./environment.yml /code/environment.yml

RUN conda config --set channel_priority strict
RUN conda config --add channels conda-forge
RUN conda env create -f environment.yml

# Make RUN commands use the new environment:
SHELL ["conda", "run", "-n", "plt_env", "/bin/bash", "-c"]

RUN pip install streamlit==1.22 Pillow lazyeval pandas

# Demonstrate the environment is activated:
RUN echo "Make sure streamlit is installed:"
RUN python -c "import streamlit; print('streamlit: ', streamlit.__version__)"

COPY . .

# The code to run when container is started:

ENTRYPOINT ["conda", "run", "--no-capture-output", "-n", "plt_env", "streamlit", "run", "", "--server.port", "7860", "--server.address", ""] 

Some of it is probably not required but it works.
