Thanks to Kit Baum, the package -stripplot- has been updated on SSC.
Stata 8.2 is required. To install or update, use -ssc- or -
adoupdate- as
appropriate.
The first version of -stripplot- was called -onewplot- and goes back
to
23 April 1999. The truncated name reflected the 8.3 filename.ext limit
that then applied to Stata ado files. Later the longer name -
onewayplot-
was used; the present name was adopted in 2005.
Originally the program was designed as an alternative to the official
command -graph, oneway- (from Stata 8 -gr7, oneway-). Later its role
became more of an alternative to the official command -dotplot-. More
recently, the popularity of similar ideas in other software (e.g. R)
has
also been a stimulus.
The update consists most visibly of a new option -separate()- for
distinguishing subsets of data points. A question from Kit Baum at the
London users' meeting last September nudged me into implementing this.
Thus users now have three possibilities for subdivision of data:
previous versions of -stripplot- included -by()- and -over() options.
There are also various other small updates and fixes to both code and
help.
The help file is detailed, with several examples and references, so I
won't expand further. Those wanting a quick sample of -stripplot-
could
try, after installation,
. sysuse auto, clear
. stripplot mpg, over(rep78) separate(foreign) stack
