In reality I have about 12 locations, which makes it impossible to print on one page and still keep it legible. That apply command would just run 'scale' on each row of your data (and I removed the first column with all the customer names so it would work). Then it packages up the results into a matrix for you. This is exactly the kind of problem it's designed to handle. – glenns heating \u0026 air greenville nc
