This R Package is dedicated to "Automatic Weather Station" (AWS) Network data spatialization. It is currently being developed by the CRA-W in the context of the Agromet Project.
In short, the aim of the Agromet project is to provide a near real-time hourly gridded datasets of weather parameters (Air temperature, rainfall, relative humidity and leaves wetness) at the resolution of 1 kmĀ² for the whole region of Wallonia
This package constitutes the core of the spatialization process of weather data. It makes an heavy use of mlr package and its unified interface for Machine Learning (ML) algorithms benchmarking.
Many vignettes documenting our development process are availbale. Check them to understand our development strategy !
You can install this package using devtools package. We highly recommand you to use packrat package for you projects relying on this package. Doing so will ensure you have a sandbox environment with all the required versions of packages needed to make it work.
As this package requires geographic/spatial capabilities, you will also need multiple system dependencies. This package was developped under a containerized Debian environment based on the rocker/tidyverse docker image. This dockerized environment is available on docker hub under the name pokyah/agrometeordocker. As stated in the docker file of our developement container, multiple Linux Debian OS dependencies are required to make our package work (full list specified in the installation instruction paragraph).
You will also of course need R to make the package works !
To do this, in debian, simply open a terminal, paste and execute the following line :
# installation of OS dependencies sudo apt-get update \ && sudo apt-get install -y software-properties-common \ && sudo apt-get update -q \ && sudo apt-get install -y \ texlive-full \ jq \ libjq-dev \ libv8-3.14-dev \ libprotobuf-dev \ protobuf-compiler \ libjq-dev \ openssh-server \ libxml2-dev \ libssl-dev \ libcurl4-openssl-dev \ libgeos-dev \ libcairo2-dev \ libudunits2-dev \ gdal-bin \ libgdal-dev \ libproj-dev \ freeglut3 \ freeglut3-dev \ mesa-common-dev \ default-jdk \ r-cran-rjava \ && sudo apt-get clean \ && sudo rm -rf /var/lib/apt/lists/ \ && sudo rm -rf /tmp/downloaded_packages/ /tmp/*.rds \
if not yet installed on your machine, simply use :
sudo apt install dirmngr
sudo apt-key adv --keyserver keys.gnupg.net --recv-key 'E19F5F87128899B192B1A2C2AD5F960A256A04AF'
sudo apt update
sudo apt install r-base
In your home folder create a file named .Rprofile
and paste these lines into it :
## Default repo local({r <- getOption("repos") r["CRAN"] <- "https://cloud.r-project.org" options(repos=r) })
packrat
allows you to install all the other packages in a sandbox environment. To do so, open your R console and type the following :
install.packages("packrat")
If you are prompted to update packages, simply select none
In your console :
mkdir <YOUR_PROJECT>
Open your R console in this folder and initialize packrat :
packrat::init( infer.dependencies = FALSE)
You are now in packrat mode for this folder. All the package you will install from this folder will be installed in the folder private library (see packrat doc for more information).
This package will allow you to download the agrometeoR package from Github.
# remotes version 2.0.4 is bugged so need to use this trick to install required version : # https://stackoverflow.com/questions/17082341/installing-older-version-of-r-package package = "https://cran.r-project.org/package=remotes&version=2.0.2" utils::install.packages(pkgs = package, repos = NULL)
In your R console :
remotes::install_github("pokyah/agrometeoR", ref = "master")
This command will also automatically install all the required R packages needed to make this package work (these are specified in the DESCRIPTION file of the package) into your project packrat private library.
This API key is required to get data from the PAMESEB database. At the root of your project folder, create a .Renviron
file and paste the following line :
AGROMET_API_V1_KEY = <YOUR_TOKEN>
You are now ready to go !
