Thanks for the tip - avoiding parsing on the Tcl side would be great! I need to take a look at that possibility. Never done that before as using just dotTcl has been working fast enough for me the past fifteen years. ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
