OOPS!!!..
This installed an old one... i.e 
/etc/apt/sources.list had a old reference to R 
To use latest R
 
follow..
 
https://www.digitalocean.com/community/tutorials/how-to-set-up-r-on-ubuntu-14-04
 
 
$ sudo sh -c 'echo "deb http://cran.rstudio.com/bin/linux/ubuntu trusty/" >> /etc/apt/sources.list'
 
To authenticate packages downloaded using APT, we have to add a public key. The Ubuntu archives on CRAN are signed with a key with ID E084DAB9. Add this key to your system.
  • gpg --keyserver keyserver.ubuntu.com --recv-key E084DAB9
Next we need to add the key to apt.
  • gpg -a --export E084DAB9 | sudo apt-key add -

Now that APT has been set up properly, we are ready to use it to install R.
First, we need to update the list of available packages since we updated the sources list.
  • sudo apt-get update
Now we can install R. We use the -y flag to automatically answer Yes when asked if we are sure we want to download the package.
  • sudo apt-get -y install r-base

ScoreCard Model using R

Example R Notebook for ScoreCard Model One often receives mailers on pre-approved loan based on creditworthiness. When one applies for credit, often it’s approved, sometimes it isn’t... Have you ever wondered how exactly the decision to approve a loan is done?  Was the bank able to clearly articulate the rationale of their decision to decline? To ensure fairness and transparency, there are compliance rules which mandates Banks to have such a mechanism. The Federal Trade Commission (FTC), the nation’s(US) consumer protection agency, enforces the Equal Credit Opportunity Act (ECOA), which prohibits credit discrimination on the basis of race, color, religion, national origin, sex, marital status,age, or because you get public assistance. In BFS, often underwriter needs to decide the creditworthiness of an applicant. Among other things, a scorecard is typically in place and long been used. Now with data deluge and better processing power many Analytical models are also used.
