I am writing a GUI for my R script. It is a very basic form consisting of
textboxes and buttons. 
I tried to run the following example to learn how to read value currently
entered into the textbox:
( it requires tcltk/tcltk2 packages )
    # Create the widgets
    base <- tktoplevel()
    list <- tklistbox(base, width = 20, height = 5)

    entry <- tkentry(base)
    text <- tktext(base, width = 20, height = 5)
    tkpack(list, entry, text)
    # Write and read from the widgets
    writeList(list, c("Option1", "Option2", "Option3"))
    writeList(entry, "An Entry box")
    writeText(text, "A text box")
    # Will be NULL if not selected
# Destroy toplevel widget
#    tkdestroy(base)
## End(Not run)

I took it from:
When I run the example I get the following error:
"Error in function ()  : could not find function "getTextValue"

What's missing here? Is the function getTextValue() inactive/not supported
anymore? Any alternatives?
