title: rPython package fails to install on R Shiny shinyapps.io
body: <p>Do the shinyapps.io servers not have python installed? Because the package <a href="http://rpython.r-forge.r-project.org/" rel="nofollow noreferrer">rPython</a> fails to install and it needs python installed. I find it odd if the answer is no because RStudio itself has <a href="http://www.r-bloggers.com/controlling-rstudio-python-child-processes/" rel="nofollow noreferrer">python support</a>.  </p>
  
  <p>Will the shinyapps.io servers ever have python support or is there a workaround? I'd like my published shiny app to call a python script.</p>
  
  <p>Below the installation of rPython on shinyapps.io fails even though it installed and ran fine when done locally (I have python installed obviously).   </p>
