> When we use `$SPARK_HOME/R/install-dev.sh` it uses the default system R.
> However, a user might have locally installed their own version of R. There
> should be a way to specify which R version to use.
> I have fixed this in my code using the following patch:

> # R on Spark
>
> SparkR is an R package that provides a light-weight frontend to use Spark
> from R.
> +### Installing sparkR
> +
> +Libraries of sparkR need to be created in `$SPARK_HOME/R/lib`. This can be
> done by running the script `$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 giving the full
> path of the `$R_HOME` as the first argument to the 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
> +./install-dev.sh /home/username/R
> +```
