How do I convert factors to numeric? It's an FAQ but...
Dear R list people
I loaded a file of numbers into R and got a dataframe of factors. So I tried to convert it to numeric as per the FAQ using as.numeric(). But I'm getting errors (please see example), so what am I getting wrong?
Thanks for your time.
