PDF not displayed after knitting Rmd file

When I knit an .Rmd file it does not automatically display the final pdf file in a new window or in Viewer Pane. The PDF file is generated and can be opened fine if double clicked, but I want to be able to see it within RStudio. If I knit the same file to HTML it does show up in a new window or in Viewer Pane (tried with both settings.)

Any thoughts? Thank you.

Tested with this .Rmd:

This is some text.

Try installing tinytex.

Thanks williaml. It's already installed.

Found the issue:

Global Options > Sweave > Preview PDF after compile using was set to No viewer. Selecting Rstudio Viewer solved the problem.
