...'d greatly appreciate feedback or other ideas! Implementation: -- the variable inclose is now in the device specific structure (why was it global?) After the window is mapped, inclose is TRUE until the window is destroyed explicitly or a DestroyNotify event has been received. -- the deviceSpecific pointer is set to NULL after the memory has been freed. This (side?) effect is used in X11_Locator to detect the closing of the current device which _must_ lead to an error. -- the if statement to handle events of type DestroyEvent is added to handleEvent -- when the user closes the devi...

I discovered a little problem when using the Windows NT release of R 1.0.1, and it's still there in R 1.1.0. The boiled down version is this: I want to draw the following plot and put it into a Postscript file: x <- c(1,2,3,4); y1 <- c(1,2,3,4); y2 <- c(2,2,2,2) Fred <- c(1,2) postscript(file="d:/Bob/Papers/IFM/try2.ps") plot(x,y1, type="l")
