title: Unable to save R script as an R file
body: <p>When trying to save a script as an R file, I am not able to. The save as window opens, but the 'save as type' bar below the 'file name' bar is blocked/greyed-out. I am, however, able to save the script as an unreadable file. When I open it again to continue working on it, it cannot run. I then have to copy paste it to a new script to continue working on it and running the commands. I cannot seem to find many questions on the internet relating to this problem except this one: <a href="https://support.rstudio.com/hc/en-us/community/posts/219163988-Can-not-save-new-R-script-save-as-bar-grayed-out" rel="nofollow noreferrer">https://support.rstudio.com/hc/en-us/community/posts/219163988-Can-not-save-new-R-script-save-as-bar-grayed-out</a>. </p>
  
  <p>I have tried <code>save()</code> which does not work. I have also uninstalled R and installed the latest version of R, this does not help either. Would anyone know how to fix this problem so that I can save it as an R file?</p>
