Dear All!

my data is on pairs of countries, i and j, e.g.:

y,i,j
1,AUT,BEL
2,AUT,GER
3,BEL,GER

I would like to create a dummy (indicator) variable for use in regression
(using factor?), such that it takes the value of 1 if the country is in the
pair (i.e. EITHER an i-country OR an j-country).

Thank you for your help,
Serguei
