Hello everyone,

I want make a variable selection from a dataframe, but when I build this new object (using cbind) the new table (which is a matrix) I lost all the original factor names in the variables. I get 1,2,3....

Someone would be so kind and tell me if there's is a ny way to get variables in a dataframe, but not changing these factor to numbers?

please provide a reproducible example as written in the posting guide.
