If you can figure out how to wire a Tcl channel to the R console, then I suppose it could be made to work.
What might be easier to implement (currently it does not work) would be something like tcl(cat, "Hello, World") It almost works: > .Tcl(paste(.Tcl.callback(cat), "foo\\n")) foo <Tcl> > ..but apparently there is a discrepancy between the single-string return value from .Tcl.callback(cat) and what .Tcl.objv expects. >> library(tcltk) >> tcl("puts", "stdout", "Hello, World") >> > Error in structure(.External("dotTclObjv", objv, PACKAGE = "tcltk"), > class = "tclObj") : > [tcl] can not find channel named "stdout". > >> .Tcl('puts stdout "Hello, World"') >> > Error in structure(.External("dotTcl", ..., PACKAGE = "tcltk"), class > = "tclObj") : > [tcl] can not find channel named "stdout". > >> R.version.string # Windows Vista >> > [1] "R version 2.7.0 RC (2008-04-17 r45367)" > > ______________________________________________ > R-help@r-project.org mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code. > -- O__ ---- Peter Dalgaard Ă˜ster Farimagsgade 5, Entr.B c/ /'_ --- Dept. of Biostatistics PO Box 2099, 1014 Cph.
