First of all note that -byvar- is a user written command (and pretty
old). The way you use it can also be done with official Stata's -by- or
-bysort- commands. You can get the dataset you want by using a
combination of -contract-, -reshape-, and -egen-, as is shown in the
example below. Also see the helpfiles of those commands for the
details.
*------------- begin example -------------
webuse hiv, clear
bys cd4: tab hiv [fw=f]
contract hiv cd4 [fw=f]
reshape wide _freq, i(cd4) j(hiv)
egen tot = rowtotal(_freq0 _freq1)
list
*------------ end example ----------------
(For more on how to use examples I sent to the Statalist, see
http://home.fsw.vu.nl/m.buis/stata/exampleFAQ.html )
Hope this helps,
Maarten
