download and unzip the compressed folder jwsacruncher-standalone-3.x.y-windows-x86_64.zip, if you use Windows…

R packages

First, if needed, get Java version higher than 17

Easy: Java 21 is embedded in the GUI file you’ve just installed: you have it !!

You just need it to link to R via R studio

• Once jdemetra-standalone-3.x.y-windows-x86_64.zip is unzipped, the Java will be in located in C:-standalone-3.x.y-windows-x86_64.2+13-jre (path to be adapted to your computer/server): this location must be declared in R.

• Run this code at the beginning of your programs

Sys.setenv(“JAVA_HOME” = “…/jdemetra-standalone-3.x.y-windows-x86_64/nbdemetra/jdk-21.0.2+13-jre”)

or (better)

• declare it “permanently” is the Renviron file (where environment variables specific to R are stored), following the steps below:

    - in the R console run file.edit("~/.Renviron")
  
    - in the file that opens add the line :
  

  JAVA_HOME= “C:/Software/jdemetra-standalone-3.x.y-windows-x86_64/nbdemetra/jdk-21.0.2+13-jre”

    - save the file and restart R
  

Install the required R packages

# from R Universe
install.packages("rjd3toolkit", repos = c("https://rjdverse.r-universe.dev", "https://cloud.r-project.org"))
install.packages("rjd3x13", repos = c("https://rjdverse.r-universe.dev", "https://cloud.r-project.org"))
