Does anyone know why savePlot can’t save to pdf in linux by default?
> savePlot("rv-3.pdf", type="pdf")
Error in match.arg(type) :
'arg' should be one of “png”, “jpeg”, “tiff”, “bmp”
lizard:~images$ R --version
R version 2.14.1 (2011-12-22)

?savePlotis pretty clear about this:Hence you start with a raster representation and therefore can only go to a raster representation. It would be somewhat perverse to pipe a raster version of the plot in a PDF, which is a vector format (yes I know you can have rasters inside PDFs).
The functionality is limited to cario-based
X11devices and the documentation refers to copying the “on screen” representation hence the restrictions.I suppose the other Answer to your question is: that functionality has not been implemented yet.
