*--------------- begin example -----------------
sysuse auto, clear
recode rep78 1 = 2
levelsof rep78
local levs `"`r(levels)'"'

gen resid = .
foreach lev of local levs {
	reg price mpg foreign if rep78 == `lev'
	predict resid_t if e(sample), resid 
	replace resid = resid_t if e(sample)
	twoway scatter resid_t mpg, name(gr_`lev')
	drop resid_t
}
*----------------- end example -------------------
