st: various changes on SSC
Thanks to the redoubtable Kit Baum, various
packages of mine have been added to or
revised on SSC.
All these require Stata 8. To install
or replace, please use -ssc-.
Richard Campbell asked a question for which my
answer centred on the use of -mylabels-. His
example was a lot better than that previously
featured in the help, so I've added it to
-scat3- is a port to Stata 8 of a program -gr3-
by Bill Gould which offers crude 3-dimensional
graphics (his words, and mine too). Neither
contours, nor perspective (wireframe) views, are
produced, but projections of 3D scatter plots
on to a plane.
-gr3- was published in STB-2 in 1991 and
revised in STB-12 in 1993. It has been (partially)
broken since Stata 3.1 (although the work-around
for that was not difficult) and it always had
a small but noticeable cosmetic problem of
marginal axis labels and ticks which needed
Stage to be employed for removal. (Stage was
the Stata Techies' Amiable Graph Editor, or
some similar acronym or abbreviation.)
Porting this was a lot of fun, re-discovering
the syntax of Stata 2.1 and wondering how best
to map the clever Gould tricks of 1991 into
mundane version 8 -graph- tricks of 2004.
Be assured that having ported this, I have
no plans to add any major bells or whistles,
but it is there for play if it suits. I
guess that Bill would say the same.
Hildegard Schaeper found a bug and suggested
Thanks therefore to Richard Campbell, Bill
Gould and Hildegard Schaeper whose work
underlies these changes.
