Dear all, I have 1980~1990 eleven datas, every year have three variables, wage gender(1=female, 2=male) race(1=black, 2=white) My original commands is: fig2b<-reldist(y=mu1990$wage,yo=mu1980$wage,.......) I have three questions: 1. If I want to appoint y=women's wage in 1990 yo=women's wage in 1980 2. If I want to appoint y=women's wage in 1990 yo=men's wage in 1990 3. If I want to appoint y=black women's wage in 1990 yo=white women's wage in 1990 How can I modify the commands? All help highly appreciated.

[R] Odp: How can I appoint a small part of the whole data
