New Delhi UseRs March 2013 MeetUp #rstats

The fifth New Delhi UseRs Meet Up happened at Mimir Tech’s premises in Green Park, New Delhi. I presented on using GUIs for easier transitioning to R from other software but limited it to Deducer (for data visualization -specifically templates and facets in GGPLOT) and Rattle (for Data Mining). We also discussed a couple of things including how to apply R in other business domains, and open source alternatives to Meetup.com .

Running R and RStudio Server on Red Hat Linux RHEL #rstats

Installing R

  • sudo rpm -ivh http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm

(OR sudo rpm -ivh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm )

THEN

  • sudo yum install R

THEN

  • sudo R

(and to paste in Linux Window- just use Shift + Insert)

To Install RStudio (from http://www.rstudio.com/ide/download/server)

32-bit

  •  wget http://download2.rstudio.org/rstudio-server-0.97.320-i686.rpm
  •  sudo yum install --nogpgcheck rstudio-server-0.97.320-i686.rpm

OR 64-bit

  •  wget http://download2.rstudio.org/rstudio-server-0.97.320-x86_64.rpm
  •  sudo yum install --nogpgcheck rstudio-server-0.97.320-x86_64.rpm

Then

  • sudo rstudio-server verify-installation

Changing Firewalls in your RHEL

-Change to Root

  • sudo bash

-Change directory

  • cd etc/sysconfig

-Read Iptables ( or firewalls file)

  • vi iptables

( to quite vi , press escape, then colon :  then q )

-Change Iptables to open port 8787

  • /sbin/iptables -A INPUT -p tcp --dport 8787 -j ACCEPT

Add new user name (here newuser1)

  • sudo useradd newuser1

Change password in new user name

  • sudo passwd newuser1

Now just login to IPADDRESS:8787 with user name and password above

Book Review- Predictive Analytics: The Power to Predict Who Will Click, Buy, Lie, or Die

I recently read a review copy of Dr Eric Siegel’s new book Predictive Analytics: The Power to Predict Who Will Click, Buy, Lie, or Die.

(Disclaimer-I have interviewed Eric here in September 2009, and we have been in touch over the years as his Predictive Analytics Conference became a blog partner and then a sponsor here at Decisionstats.com PAWCON also took off, becoming the biggest brand in independent analytics conferences)

So it was with a slight note of optimism that I opened this book, and it has so far exceeded my expectations. This is a very lucidly writtern, well explained book that can help people at all levels for analytics. There is a wealth of information here in a wide variety of business domains, and the beautifully designed book also has great tables, examples, and quotes, cartoons to make a very readable case for predictive analytics. Of course, Eric has some views, he loves ensemble modeling, conversion uplift models, privacy concerns, and his background in academics help explain even technical things very elaborately and in an interesting manner.

And at $14,6 it is quite a steal from Amazon. So buy a copy and read it. I would recommend it for helping build a case for predictive analytics , evangelizing to clients, and even to students in grad school programs. This is how analytics books should be , easy to read, and lucid to remember and practical to execute!

Springer Book on Seamless R and C++ Integration with Rcpp and Workshop on Rcpp #rstats

The talented Dirk Eddelbuettel has just announced that his new book is coming out this year. I would recommend this book for anyone trying to use R for analytics, Big Data or customized use cases especially if they have a need to speed up the computation times. Rcpp can speed up R by a huge magnitude, and thats because C++ comes closer to the metal.

If you are a business analyst who knows a bit of R, but always were intimidated by C++ programming, well this is the right how to do book for you.

Ajay- Describe the story so far for Gramener. What have been the key turning points ?

Naveen- All founders of Gramener are first generation entrepreneurs, started our careers with IBM were very successful in our corporate jobs with hefty pay packages, but always at the back of the mind can’t we work our ourselves and have FUN.

With this thought in mind 6 of us got together in 2010 to lay foundation for Gramener, with our consulting experience we wanted to get into business analytics , but soon we realized that there are lot many people who are doing great analytics but not an effective way of presentation, we wanted to establish niche for ourselves and create an offering to make “Data Consumption” easy and joyful.

 

Our significant milestone was Airtel Continue reading “Interview – Naveen Gattu, COO and Co-Founder at Gramener #dataviz”
