R devel - Apr 2007 - Implementation of pretty

Hi,

I'm trying to track down any references for the implementation of
pretty (or grid.pretty) in R.  Is it original work?

Thanks,

Hadley

Much of it is.  The original version, say R version 0.01, may
have been based on some reference, but we have added quite a few extra tweaks,
where in my case I sat down with a piece of paper, considered
and transformed some inequalities and also did computer
experiments additionally. 
I've even started to make more coherent notes eventually, but
not electronically, and hence no tech.report /  publication / ...

 { Did you really want to know this :-) }
