hastistics

Sort of LINQ for Haskell. It was developed as part of the course "Programming language concepts" at the University of Applied Sciences of Northwestern Switzerland.

Functionality

import Hastistics
import Hastistics.Data.CSV

result = select $
         valueOf "Gender" $ avgOf "Mark" $
         groupBy "Gender" $
         from (csvTable [toHSString, toHSDouble] csvString)

If you now print this, you get something like

+----------------------+----------------------+
| "Gender"             | "Average of Mark"    |
+----------------------+----------------------+
| M                    | 4.4375               |
| W                    | 4.75                 |
