This topic shows how to create a Conda environment for R packages, with R-4.0.5 for OML4R compatibility, and install the forecast and ggplot2 packages.

1. Run the following command to create the environment for R by the name myrenv and also install the packages forecast and ggplot2:

   %conda
   
   create -n myrenv -c conda-forge --override-channels --strict-channel-priority r-base=4 r-forecast r-ggplot2

   In this example, we are using the conda-forge channel to install the R packages.
   In this command:

   • -n: This is the name of the environment. In this example, it is myrenv.
   • -c: This is the channel name. In this example, it is conda-forge.
   • --override-channels: This argument ensures that the system does not search default, and requires a channel to be mentioned.
   • --strict-channel-priority: This argument ensures that packages in lower priority channels are not considered if a package with the same name appears in a higher priority channel. In this example, the priority is given to R-4.0.5, forecast, and ggplot2.
   The command returns the following:

2. You may now verify the Conda environment for R that you just created. Run the following command in a %conda paragraph to view the list of environments.

   Note that the myrenv environment is now listed along with the mypyenv in the output.

   Note that the asterisk (*) is against the mypyenv, indicating that this environment is active currently.
