I'm starting to work with rMaps (following this example), and it's a great package. I'd like to include the results in a document, either by exporting the result to a .jpeg, .png or other graphical format, or by rendering the output directly into a LaTeX document (using sweave or knitr). However, after searching a lot, I've found no way to do it.
So, the question is: Is there a (preferibly simple) way to export rMaps result (ichoropleth, crosslet and/or Leaflet) directly to an image file (or set of files)?
