Probably have to check for the missing issue brought up by Jacob?

sysuse auto, clear
egen myMean = rowmean(rep78 he) if !missing(rep78, he)
l r h myM in 6/8

Given any dataset of all numeric variables, I want to generate a new
variable called myMean, which is the arithmetic mean (the average)
across all the variables. The program below solves this problem. But
surely there is a one-line command that will perform this task in
Stata?

yes: -egen myMean = rowmean(var1 var2 foo bar etc)-

Hope this helps,
Maarten
