R-beta: Switching between plots without erasing them.
I have a question relating to switching between plots within the graphics window [x11()]. If this is not appropriate for this mailing list then please let me know. What I am doing now: Opening a graphics window and setting two plot regions [ie with par(mfrow=c(2,1))]. In the top section there is a plot with a set of points which represent river gauges located by latitude and longitude pairs. These points are global in extent so I am also using continent boundaries from a data set found on Statlib. Because there are so many points this takes some time to draw. Using the identify() function a point is selected and in the lower plot a time series is displayed from that particular river gauge. This is in a loop which allows repeated clicks on the map and time series plots. Each time through the loop, the map must be redrawn. I would like to do the following: I would like to keep the upper plot (the map) intact while being able to completely redraw the lower plot (the time series). Is there some way I can return to the upper plot and invoke the identify function without erasing the map? The function frame() erases the plot. I suppose the alternative would be to have two independent graphics windows, but I am not sure if that is possible within R.
