[R-SIG-Mac] GUI bracket-matching and window positioning

[Tim Cole]

A couple of queries-comments about the Mac gui.

1. I'm curious what determines where new editor and quartz windows are 
positioned. Usually editor windows appear in the middle of my screen, 
and successive windows in the session shift down and to the right. My 
impression is that the last window position is remembered between 
sessions. Is there a way to reset the position of the initial window?

2. Quartz windows always open bottom left on my screen, irrespective of 
the preference setting. I've mentioned this before, but the behaviour 
has not changed. Am I altering the preference setting incorrectly, or is 
it broken?

3. I'm much enjoying the new gui editor. I've noticed that the following 
arcane bit of code defeats the bracket balancer, because some of the 
brackets are quoted and others aren't. Note that all the quote 
characters are single quotes.

     b <- 'b+c'
     paste('(a', ifelse(!is.null(b), paste('-(', b, '))', sep=''), ')'), 
sep='')

My setup:
R version 2.13.1 (2011-07-08)
[R.app GUI 1.41 (5874) i386-apple-darwin9.8.0]
