You may want to re-read some of the available code examples. What you did is
fundamentally broken -- you do not pass strings with variables names inside.
You need to define some variables via the tclVar() function, and you can
access the values of those variables in non-tcltk expressions with tclvalue().
What you want it probably close to this -- it uses menubuttons rather than
checkbuttons but is the closest example I had hanging around here:
color <- tclVar("blue")
long.color <- tclVar(paste("Status is", tclvalue(color)))
for (i in c("red", "green", "blue"))
tkadd(m, "radio", label=i, variable=color, value=i,
command=function(){
cat("Background is", tclvalue(color), "\n")
tclvalue(long.color) <- paste("Status is", tclvalue(color))
})
