rCharts creates an iFrame so it can only be viewed in a browser (because it's basically html). I had a similar problem. I wanted a pdf that contained a bunch of rCharts, so I wrote some R code that creates an html page and sticks the rCharts into the appropriate locations (dealing with spacing, extra text and headers, styling, etc). Then it's easy to turn the html into a pdf.
