I have been using Tinn-R with R without any problems but when I try to use it with REvolution R I get the following error message when Tinn-R runs the configuration script and gets to the trDDEInstall() function: ## Start DDE trDDEInstall()> trDDEInstall()Error in structure(.External("dotTcl", ..., PACKAGE = "tcltk"), class = "tclObj") : [tcl] invalid command name "dde". In addition: Warning message: In tclRequire("dde", warn = TRUE) : Tcl package 'dde' not found I have not found anything about this on the Tinn-R forum and have had no repsonse from the REvolution R forum. I have checked other R-Help queries but these relate to adding the code for .trPaths which I already have. Does anyone know how to solve this problem? [[alternative HTML version deleted]]

[R] Problem with Tinn-R communicating with REvolution R
Hello, DDE communication requires and additional 'dde' Tcl package. That one is installed usually with the default Tcl/Tk 8.4/8.5 under Windows, but it seems Revolution R uses a different install where the dde Tcl package is not installed, or is not accessible where Tcl think it should be. One solution would be to install a full Tcl/Tk from ActiveState and use it instead (read Windows FAQ, I think instruction is there).
