PODeploying Django with Rpy2 to Heroku
text
Body
copied!<p>I am a novice hitting the limits of my ability to get something small with django and rpy2 working on Heroku. In particular, I am trying to test the concurrency vulnerability rpy2 creates, to see if Heroku protects against it (via dyno isolation?).</p> <p>Deploying the django sample is fine, but adding rpy2 hits an unsatisified R dependency</p> <pre><code>git push heroku master Counting objects: 11, done.

Anyone have an idea how to resolve the above dependency conflict (because I want to use the two together eventually), or whether R and python interaction cannot scale safely on Heroku?</p>
