Bear me if this is a naive question.
I have a dataframe, all lists inside it are factors. When I use
as.matrix(df) to convert, I get a character matrix while my intention is to
get numeric matrix. I can make the convertion iteratively by each list but
I do think there is some more elegant way of doing this.
please let me know if I missed somthing there.
Thanks in advance.
