I am using a preview release of RStudio (1.2.907) on Debian 9. When I use the help pane to navigate to some PDF vignette and click on it, the PDF file is not opened in the PDF viewer. Instead, I am offered a download dialogue.
Files are opened in the PDF viewer when I use
vignette(...) or click on a PDF file in the file pane. However, in both cases the PDF viewer is opened in the background, which is slightly inconvenient.
Are there any settings to change this behavior?
