search for: edad11

Hi Need a little help. This is easy question, but i?m new to R. I want to subset a data frame called vef1 using a variable that is a factor called edad11, 0 if under 11 years, 1 otherwise. I tried: vef1.sub<-subset(vef1, edad11==0) The code runs correctly but i get a empty dataframe. If i use this code in Deducer everything is OK. Can you help me? Thanks in advance Antonio Sousa Portugal
