I suspect you have two copies of the Symbol font on you machine, one of which is corrupt, and that AcrobatReader is smarter than RStudio in deciding which one to access. Use Fontbook.app (possibily in /Applications/Utilities/ if not in /Applications/ ) to see if my guess is correct ... and if it is, then delete the one that displays a blank page.
