In-Code Documentation for ‘GAMS’

R package goxygen, version 1.4.5

Purpose and Functionality

A collection of tools which extract a model documentation from ‘GAMS’ code and comments. In order to use the package you need to install ‘pandoc’ and ‘pandoc-citeproc’ first (https://pandoc.org/).

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("goxygen")

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

update.packages()

Tutorial

The package comes with a vignette describing the basic functionality of the package and how to use it. You can load it with the following command (the package needs to be installed):

vignette("goxygen") # Creating GAMS model documentations with goxygen
