Dear all,

I am using the "productivity" package to measure shadow prices. There are 26 observations in my sample and I use 3 inputs and 1 output. Unfortunately, when I am running R with the command above, I am only getting 1 set of shadow prices instead of 26 sets of shadow prices. How can I fix this problem?

Help or tips will be strongly appreciated!
