One way that u might have thought of is to create plot in PDF in R and the
use pdftools.
Additionally one can also think of running R script using R CMD and then
using pdftools in a .sh script file if u r in linux.
I am not aware of pdftools capability in R.

Michael,
Although this is a rather old post I'm responding to, I recently came across
it and have a suggestions for getting rid of the legend. Simply modify the
code associated with the function and stuff it into a new function,
edm-function (x = seq(0, 1, length.out = nrow(z)), y = seq(0, 1,
Check whether x, y, or glm have been redefined. If not, restart R.
