Hi, what does your R-prompt show when you just type:
urban$x and hit ENTER. The error message suggests that urban$x does not contain any numeric elements. So either it is empty or it contains, for example, a factor-coded (dummy-like) variable. We will probably need more information to help you. Further, please follow the posting guide and supply self-contained code, i.e. a code snippet that reproduces the error you face, including a sample of your real or simulated data.
