Follow the steps below:
<h4 class="formatter-title wiki-paragraph-4" id="paragraph-step-1-start-r">Step 1: Start R</h4>
Windows: Start -> All Programs -> R.
MACOS X: Click on R icon in the Applications folder.
Linux: Open shell and type R then press the Enter key.
<h4 class="formatter-title wiki-paragraph-4" id="paragraph-step-2-import-rquery-environment-in-r">Step 2: Import RQuery environment in R</h4>
Windows: File->Source R code -> specify RQuery-windows.r file path, you downloaded
Mac: File-> Source File ->specify RQuery-mac.r file path, you downloaded
Linux: Use the source command from R console. This command can also be used on Windows and Mac
Code R :
source("Indicate the absolute path to RQuery-xxx.r")
<h4 class="formatter-title wiki-paragraph-4" id="paragraph-step-3-install-the-r-packages-required-for-rquery">Step 3: Install the R packages required for RQuery </h4>
You just have to use the function rquery.checkEnv included in the RQuery-xxx.r file. An internet connection is required.
Type this command line in R :
Code R :
rquery.checkEnv()
rquery.checkEnv install automatically all R packages require to use RQuery.
During the installation process, a window will appear asking you to select a mirror site from which R packages will be downloaded. Preferably select your contry. The selected country will only influence the download speed.
The installation process may take 2-5min depending on your internet connection.
If you use Linux OS, it is necessary to install rgl package from linux console (not from R console) in order to make 3D graphics.
The code is :
Code BASH :
apt-get install r-cran-rgl
<h4 class="formatter-title wiki-paragraph-4" id="paragraph-etape-4-your-turn">Etape 4: Your turn</h4>
