John, does it have to be PDF? Unfortunately, PDF is not easy to deal with in platform-independent way (and generally as well - of all the systems only macOS has native support for it). If you really have no other choice, my only suggestion would be to use poppler to render it so it can be displayed by R directly. Anything else is a bit more convoluted like embedding it in a webpage and hoping the browser has PDF support, but that tends to be pretty clumsy.
