st: smart averaging

Hi,
I have the following problem I have been unable to decipher. I have the
following data set:
id year income
1 2006 100
1 2007 50
1 2008 .
1 2009 .
2 2006 50
2 2007 50
2 2008 50
2 2009 50
I want to average the income variable for those four years. I tried to use
the following command:
bys id: egen average_inc = mean(income) if inrange( year,2006,2009)
However, that averages person 1's income, too. I need to average just
person 2's income.
Can anyone suggest how to do that? Thank you in advance.
Murat
