I use 1.7.0 version under Windows XP. Problem: When graphics device history recording function turned on, suppose I source a file containing lines: plot(graph1) plot(graph2) I see the graph2 in the graphic device, assuming graph2 is the last plot in the file. Now using "Previous" under history menu, I get graph1 as expected. But after that, using "Next" does not show graph2. Is this a normal behavior? If so how do you get back to graph2? I have observed the same behavior in 1.6.2.
R does not know the plot is finished until you go on to the next one. So you have to explicitly add the current state of the current plot to the history, when it will work.
