Odp: How can I appoint a small part of the whole data
Hi use any of suitable selection ways that are in R. E.g. data[data$gender==1, ] selects only female values data$wage[(data$gender==1) & (data$race=1)] selects black female wages. and see also ?subset Regards Petr r-help-bounces at r-project.org napsal dne 03.09.2009 10:51:59:
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.
Best,
Yichih
