Looks like your data are not numeric. Examine your data with the str function and troubleshoot your process for reading in data. Step through the code one line at a time and see how the data looks at each step. 

Also, you really need to read the Posting Guide and follow the advice there. If you had done so, we could be more specific about how to fix your problem.
