R, Python: install packages on rpy2

Question

I\'m using R in my Python script through the rpy2 library and I need a package that is not in the default installation of R. How can I install it?

Answer 1

Ricardo's answer no longer works.

To install from Python:

from rpy2.robjects.packages import importr
utils = importr('utils')
utils.install_packages('DirichletReg')

That utils package is the R.utils package whose documentation can be found here: https://CRAN.R-project.org/package=R.utils

As of my last edit, the documentation still says to do this.
