You create an image as image create Rplot ?name? The current device is used, and the current device is closed when the image is created (unless there is an error, in which case the device may remain open). For X11 the device should be XImage (a new variant of X11). For Windows, the device must be win.metafile with no file argument, which means the result is sent to the clipboard. The metafile is retrieved from the clipboard and placed in the Rplot image; this means that the clibboard is always modified when an Rplot image is created on windows (a gross hack, but it allows the windows device code to be used with no modification). Here is a very simple example suitable for pasting into R: if (Sys.info()["sysname"] == "Windows") { my.tkdev <- function() win.metafile(width=4,height=4) } else { my.tkdev <- function() .Internal(X11("XImage", 480, 480, 12, 1, getOption("X11colortype"), 256)) } my.tkdev() plot(1:20) .Tcl("image create Rplot fred") base<-tktoplevel() lab<-tklabel(base,image="fred") bb<-1 f<-function(...) { b <- as.numeric(tclvar$bb) if (b != bb) { bb <<- b my.tkdev() plot(1:20,(1:20)^b) .Tcl("image create Rplot fred") } } s <- tkscale(base, command=f, from=0.05, to=2.00, variable="bb", showvalue=F, resolution=0.05, orient="horiz") tkpack(lab, s) Performance under X11 is less than ideal since it relies on copying an image from the server to the client and then back again. But there is no visible flicker, at least on Linux. On windows the performance is also not ideal and there is occasional flicker, which could probably be avoided by playing the metafile to a pixmap and then blasting in the pixmap with a single BitBlt, but I haven't tried that yet. This is a temporary hack at best--it would be better to use a mechanism in which the content is drawn from the display list, and this could be done by abstracting out the drawing code in the driver so it can be used in any drawable.
