Why do people call things they do not understand 'strange', and use
subject lines that fail to mention key facts (the use of active
bindings)?
Are you saving the workspace? That will access the active binding (twice,
I think). With
.Last <- function() rm(newq, envir=.GlobalEnv)
it should work. I tried
invisible(makeActiveBinding("newq", function(...) cat("OK\n"), .GlobalEnv))
.Last <- function() rm(newq, envir=.GlobalEnv)
successfully.

and something odd is happening. I saw this w/ a couple versions of R 2.7.x :
First, I created an environment variable inside my .Rprofile (quoted below).
The variable itself works just fine. Here's the strange thing: when I invoke
q() or hit <CMD>-q to quit R.app , R throws up a new Untitled window that
looks like it might be a new quartz window, then goes ahead and quits.
myRprofile: (ignoring lines which work and do NOT affect the quit() behavior.
I tested extensively and only this binding makes a difference)
makeActiveBinding("newq", function(...) { quartz() ; par(cex=0.75)},
.GlobalEnv)->nullity
rm(nullity)
I'd just wrap the call in invisible().
A couple notes: I redirect to the variable 'nullity' so that R.app won't
throw anything onto the console window. I put the ellipsis in because
otherwise I get a Warning about unused or missing arguments to function().
I also tried putting the line
rm(newq)
into .Last, but that didn't help either.
Did you not get an error?
thanks for advice.
Carl
