The R initiative of Decision Deck proposes to use the R statistical environment, coupled with the MCDA package, to support all the steps of the MCDA process.
The MCDA package for R contains functions which can be useful to support the analyst in this complex process, and which should facilitate his dialoge with the decision maker(s).
After having installed the R environment, install the R package by typing
in the command prompt of R. This will download the latest stable version from the CRAN repositories.
We have written a tutorial which details the use of the MCDA R package in the various steps of a decision aiding process.
To contribute to the package, please clone the source of the latest version of the package available here : https://github.com/paterijk/MCDA. We would really appreciate if contributors would contact the authors of the package before implementing any new functions.
