Installing in a Conda environment

[gkaf89]

When installing this package collection in a Conda environment, I noticed that it depends on the R package R.utils and on a few other libraries.

This is the specification of the Conda environment I use to install the required libraries:

name: R
channels:
- conda-forge
dependencies:
- conda-forge::glpk
- conda-forge::libxml2
- conda-forge::openssl
- conda-forge::r-base
- conda-forge::r-packrat

It would be useful if this information was available in the installation instructions.
