Graphics device history recording problem (Previous and Next utilities) - R-help

Wed, May 21, 2003 5:40 AM #

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.

Thank you for your input.

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.

I don't see this.  Could you post exactly what you did, in what order?
Are you using MDI (one big window holding smaller subwindows) or SDI
(all separate windows)?
