You'll probably need to send your cmdfile.R to see what is in it, as 
that is where the problem likely is.  However, if you do something 


in your cmdfile.R, you will get a pdf file of the plot saved in the 
directory where you ran your script.  Note that you need to open a 
device like pdf, png, etc. for plots to be saved.  They aren't saved
