title: I cannot download pdf output for beamer presentation in Rstudio
body: <p>I am using Rmarkdown to prepare a beamer presentation. When I compile the output via knitr, I can see the final compilation of the pdf document in ViewPDF. However, when I try to download it by clicking on the download button in the upper right hand corner, it does not function--I click and click, but nothing happens. Do I need to download/upgrade my current versions? I am using R 3.3.2 and have Rstudio v. 1.0.136. What should I do? </p>
