Hello,  

I think this is Sill question but it's happens......    

am$e_isell <- factor( with( am, ifelse( e_iacc == 1 & C5 == 1, 1, 0)))  

summary (am$e_isell)

   0 1

3966 296

(Ok)  

am$e_isell [4256]

[1] 1

Levels: 0 1

(OK)    

 cbind( am$e_isell[4256], am$C6[4256])

     [,1] [,2]

[1,] "2" "1"

(??)  

cbind( am$e_isell[4256])

     [,1]

[1,] "2"

(??)    

Does anyone understand why this happens?    

Atenciosamente
