[Gretl-users] graphs with R from within gretl?

Hello everybody, I'm wondering whether it could make sense to produce graphs with R, given the brand new gretl functionality to embed R commands. I would like to compare the output quality of the standard gretl approach (using gnuplot) with what embedded R would provide. However, I have no experience with R, so I need help: does anybody have a minimal script example (say, simple scatter plot of two variables) that could be run in gretl and produce the graph, ideally saveable in pdf? thanks, sven
