Installing older version of R package

Question

I am trying to use Rpy2 and ggplot2 but I get an error. After some searching for the error online, I found that the error occurs because there are changes in the ggplot2 pac

Answer 1

Using install.packages as described in another answer does not work for me.

The best alternative I found is to use function install_url from package devtools.

Another possibility that I have not explored further:

1. Download the older .tar.gz source file from the package archives.
2. Follow the steps documented on http://rtm.wustl.edu/writings/htrtargz.pdf to install it locally.
