This can be done by running the script `$SPARK_HOME/R/install-dev.sh`. +By default the above script uses the system wide installation of R. However, this can be changed to any user installed location of R by setting the environment variable `R_HOME` the full path of the base directory where R is installed, before running install-dev.sh script. +Example: +``` +# where /home/username/R is where R is installed and /home/username/R/bin contains the files R and RScript +export R_HOME=/home/username/R +./install-dev.sh +``` ### SparkR development |
