[R] adding bmp/jpg/gif to an existing plot

[Prof Brian Ripley]

Look at the R-devel development version of R

     o	The graphics engine now supports rendering of raster (bitmap)
 	images, though not all graphics devices can provide (full)
 	support.  Packages providing graphics devices (e.g., Cairo,
 	RSvgDevice, cairoDevice) will need to be reinstalled.

and

for more details (and older ways to do it less well).
