Hi, I have a dataset with many variables and observations. The variable Group has two levels: C and P, the Month variable has four levels: 0, 1, 2 and 3. I want to extract a subset of the variable Weight, considering only 1 and 3 levels for Months of the Group variable. I tried the command subset but it did not work. Any suggestions?
Tell us how you used it and how your data looks like and we may be in a position to help afterwards,.
