Using `install.packages` with conda-managed R
Installing packages outside of an R session is arguably the point of using conda.  Package management isn't something that should be done within scripts, only the loading of packages. Doing so ensures that your environment setup is somewhat robust, which should be set before you perform actual calculations.

Using conda install ... is the best way to ensure environment stability here, and, thankfully, lots of people at Bioconductor have worked very hard to make sure bioconda packages fit with the conda framework.

If you need to find packages, you can search online at https://anaconda.org, or from the command line via conda search &lt;pkg&gt;.
