Loading Input Data Files

How to Load Data Files with mrprom

In this tutorial, you will find a brief guide about loading input data files to the OPEN-PROM model. This is accomplished by utilizing the complementary mrprom R package, that is also developed by E3-Modelling.

Installing Necessary Software and Libraries

Before using the mrprom package, you'll need to install a recent version of the R language, available for download here. Furthermore, R should be added to the PATH variable of your OS, so check the instructions for Windows and Linux, respectively. After making sure that R is correctly set up on your system, launch the R console and execute the following commands:

options(repos = c(CRAN = "@CRAN@", pik = "https://rse.pik-potsdam.de/r/packages"))
devtools::install_github("GAMS-dev/gdxrrw/gdxrrw")
devtools::install_github("https://github.com/e3modelling/mrprom")

Those commands will install the mrprom package, as well as additional dependencies that are necessary for its functionality. Please note, that you may be prompted to install the RTools utility, so proceed in doing that too.

Executing the OPEN-PROM Model

As mentioned in the Task Runner Tutorial, the OPEN-PROM model can be executed by clicking Task Runner > GAMS on the Visual Studio Code menu. This will invoke the LoadMadratData.R script that utilizes the mrprom package, and processes all datasets that are necessary to successfuly run the model. If everything goes well, a number of CSV files will be stored in the root directory of OPEN-PROM, along with some additional configuration and diagnostics files that are generated by mrprom. The entire process output will be available on the Visual Studio Code terminal, so you can catch any errors, or simply monitor the R and GAMS code execution!
