[R] Save generic plot to file (before rendering to device)

[Greg Snow]

Note the warning on the help page for recordPlot.  If your colleague is using a different version of R than you there could be problems.

Another approach (or the start to one that you could build on) is the plot2script function in the TeachingDemos package (which uses recordPlot internally). 

But it is probably best to save the resulting data from the long process, that could then be quickly plotted as others have mentioned.
