[R] front-end installation guide (1.1 version)

As a new feature of Promethee 1.1, it is now possible to call Promethee as a [R] function. This usage is highly valuable for coupling codes (like a composition of functions), testing new algorithms, or generally, using an external code (available in Promethee environment) like another R function.
The requirement to use Promethee within [R], is firstly to have both Promethee and [R] installed on the same machine, and then to properly install the rJava package in [R] (see

Checking the installation

Once [R] is started,
  • load the promethee.R script available in the Promethee installation directory,
  • initialize Promethee with Promethee.init(…) function,
  • then use shell functions (…) and…)) like another R function:

More information and examples are available as comments in the promethee.R file.
It is also recommended to use the RStudio front-end environment (see in order to make the most of R in desktop usage, especially when using Promethee interface.


What is the value added of the [R] front-end compared to the regular GUI ?

Why do you recommend to use Rstudio environment ?

Can I use the web based version of RStudio ?

I understand a “Promethee code” call is just like a R function call. Ok, but what about parallelization of function calls (mclapply, foreach, …) ?

What operating systems are supported by this front-end ?
