[R] Controling a tcl/tk slider

Dear Johan,

If I understand you correctly, you want to change the position of the slider
without directly moving the "thumb." If so, you can simply change the value
of the variable associated with the slider; for example:

    top <- tktoplevel()
    Var <- tclVar("5")
    slider <- tkscale(top, from=1, to=10, showvalue=TRUE,
      variable=Var, resolution=1, orient="horizontal")

    tclvalue(Var) <- "1"

I hope that this helps,
