Thank you very much. For verification: I have to load the tcl file within my R Code at some point with tcl("source", tclfile) where the tclfile variable is the path to my *.tcl file, in the Rpad package created with tclfile <- file.path(.find.package(package = "Rpad"), "tcl", "mini1.1.tcl") Is there no tcl equivalent like useDynLib command in the NAMESPACE file for C functions? ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
