It is a general feature that (most) attributes get
dropped during subscripting. I think you need
to make your own class of object and write a
subscripting method for the class.

I am using attributes to tag a dataset with meta information. I find
that if restrict the columns of my dataset by a command such as
jj.df<-jj.df[,-c(2,6,8)] or jj.df<-jj.df[,c(8,7,9,10)]
that the attributes I set originally are dropped. Can anyone explain
why that is and whether I can stop it happening?
Regards and thank you in advance,
