I created an an empty data frame this way: forsentest<-data.frame(matrix(nrow=nod,ncol=f)).
Then I tried to assign one row of another data frame forsen to it forsentest[1,]<-forsen[1,] But the factors in forsen gets converted to numbers in forsentest which is not what I want. Is there another way around it ?
