Problem with a non-factor, non-numeric variable in a data.frame
...ue to the NA values?). How can I get R to understand that Ratio is numeric? Checking the documentation it seems you can do it with I(x), but the details are not explained. I also tried as.numeric(Ratio), and everything was turned into zeros. Any suggestions? Cheers, Alexandre Santos Neuro-MPI, Martinsread, Germany
