changing default device settings (was strange behaviour when quitting)
This does seem a lot of work to do something that could be done better
by
setHook(packageEvent("grDevices", "onLoad"),
function(...) grDevices::quartz.options(pointsize=9))
Changing cex will not do the same thing, and 'pointsize' is the preferred
way to scale all the text (and line spacings etc) for a plot device.
You could also have
newq <- function() { quartz() ; par(cex=0.75)}
options(device=newq)
or similar.

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
