Hi I am learning R currently and I having trouble structuring a program. Data consists of 1 data frame with a day of the week, a class list, and a utility score. Date Class Utility Monday Chem 85 Monday Physics 75 Tuesday Chem 95 Tuesday Math 93 Tuesday History 87 Tuesday Language 86 And so on through Friday. I want to maximize total utility (the sum) given 2 constraints: 1. The number of classes you must take each day is fixed. (Must take 1 class on Monday, 2 on Tuesday, 1 on Wednesday etc.) 2. No repeats- You can only take any given class zero or one time. Any help to go about this would be appreciated. Thank you. bhr

Homework? If so, we don't do hw here. Otherwise, we usually ask people to show us their failed coding efforts rather than expecting us to do the problem for them. Please read and follow the posting guide. Cheers, Bert
