Others have pointed out the R plot history mechanism, which is very nice. A few additions.

If you are re-running the script often and want to get rid of old windows, you can put near the top of your script

graphics.off()

You can open a graphics window -- with history enabled -- with

windows(record=TRUE)

Plot history is saved. If desired, you can clear the old history before making new plots with

.SavedPlots <- NULL
