The goal of capriv is to draw sankey charts, related tables and maps for Common Agricultural Regrionalized Impacts (CAPRI) modelling system, a large-scale economic model with a particular focus on agriculture and food markets. ![plot](inst/examples/pic/capriV.png)

## Prerequisites

### Requirements

-   Rtools: RTools is a set of programs that is required on Windows to build R packages from source.

-   TIDYKML: tidykml reads selected elements and values from KML files.
-   GDXRRW: GDXRRW is an interface between General Algebraic Modeling System (GAMS) and R, it transfers data between GAMS and R and calls gams from within R.
-   GAMS environment system: It operations on GAMS data.
-   CAPRIR: capriR is a tool for processing, visualizing and analysing both the databases and simulation results of CAPRI.

The packages can be installed with the following commands.

``` r

# Rtools is not an R package so you will need to install Rtools first if you don't have it. Install Rtools from website: https://cran.r-project.org/bin/windows/Rtools/ (according to your R version)
# check Rtools
install.packages("pkgbuild")
pkgbuild::find_rtools()

# The R devtools package allows packages that are hosted on GitHub to be installed directly from there.
install.packages("devtools")
library(devtools)
# tidykml
devtools::install_github("briatte/tidykml")
library(tidykml)

# Installation gdxrrw from GitHub
devtools::install_github("GAMS-dev/gdxrrw/gdxrrw")
#  Or installation from website: <https://support.gams.com/gdxrrw:interfacing_gams_and_r>, then download the required file and point to the specific path of the file.
install.packages("D:/public/yang/CAPRIR_Project/gdxrrw_1.0.5.zip", repos = NULL, type="source")

# Checking if gdxrrw is installed For GAXRRW to work it must be load shared libraries from the GAMS System directory.
library(gdxrrw)
# The igdx command can be used to show what GAMS system directory GDXRRW has found. 
igdx()
# if GDX library has not been loaded, tell where is located GAMS. 
igdx("D://gams//win64//24.9")

# caprir

# from Thuenen gitlab
devtools::install_git("https://git-dmz.thuenen.de/mindstep/caprir.git", force = TRUE)
# from iiasa gitlab
# devtools::install_git("https://gitlab.iiasa.ac.at/mind-step/caprir.git")

library(caprir)
```

You can install the released version of capriv from [Thünen Gitlab](https://git-dmz.thuenen.de/mindstep/capriv.git) with:

    devtools::install_git("https://git-dmz.thuenen.de/mindstep/capriv.git")

    # or from iiasa gitlab
    # devtools::install_git("https://gitlab.iiasa.ac.at/mind-step/capriv.git")

The necessary packages can be `loaded` with `library()` function as follows:

``` r
library(caprir)
```
