I d'like to have something like:


2)My second problem,

I use the run function that i have found in R TCLTK example Evaluating R Code From A Text Window in R TclTk:   run <- function() {
  code <- tclvalue(tkget(txt,"0.0","end"))   e <- try(parse(text=code))
  if (inherits(e, "try-error")) {
    tkmessageBox(message="Syntax error",


   cat("Executing from script window:",

      "-----", code, "result:", sep="\n")    print(eval(e))
topMenu <- tkmenu(tt)
tkconfigure(tt, menu=topMenu)
fileMenu <- tkmenu(topMenu, tearoff=FALSE) tkadd(topMenu, "command", label="Run",

But when I run a=mean(c(1,2,3)) I have the result on my R console but i can't access to the result. If i write a, R don't know "a".

Thanks a lot,
and so sorry for my poor english, i hope you understand my problems...
