Finally when i run

I get the below error. Any help would be appreciated.

2. stop(gettextf("package or namespace load failed for %s",

You could follow this instructions:
$ cd ~/
$ sudo -i
$ apt-get install r-cran-rjava
$ apt-get update
$ apt-get install openjdk-8-jdk
(version 8 seems to be bug free!)
$ rm -rf /usr/lib/jvm/default-java
(I personally did not have the default-java file, but you can check if it exists on your machine)
$ ln -s /usr/lib/jvm/java-8-openjdk-amd64/ /usr/lib/jvm/default-java
$ R CMD javareconf
$ R
$ install.packages(“RWeka”)
