'GAMS' Modularization Support Package

R package gms, version 0.31.2

Purpose and Functionality

A collection of tools to create, use and maintain modularized model code written in the modeling language 'GAMS' (https://www.gams.com/). Out-of-the-box 'GAMS' does not come with support for modularized model code. This package provides the tools necessary to convert a standard 'GAMS' model to a modularized one by introducing a modularized code structure together with a naming convention which emulates local environments. In addition, this package provides tools to monitor the compliance of the model code with modular coding guidelines.

Installation

For installation of the most recent package version an additional repository has to be added in R:

options(repos = c(CRAN = "@CRAN@", pik = "https://rse.pik-potsdam.de/r/packages"))

The additional repository can be made available permanently by adding the line above to a file called .Rprofile stored in the home folder of your system (Sys.glob("~") in R returns the home directory).

After that the most recent version of the package can be installed using install.packages:

install.packages("gms")

Package updates can be installed using update.packages (make sure that the additional repository has been added before running that command):

update.packages()
