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.
