R Journal Dec 2010 and R for Business Analytics

A Bold GNU Head

Image via Wikipedia

I almost missed out on the R Journal for this month- great reading,

and I liked Dr Hadley’s article on stringr package the best. Really really useful package and nice writing too

http://journal.r-project.org/archive/2010-2/RJournal_2010-2_Wickham.pdf

(incidentally I just downloaded a local copy of his ggplot website at http://had.co.nz/ggplot2/ggplot-static.zip

I aim to really read that one up

Okay, announcement time

I just signed a contract with Springer for a book on R, some what in first half of 2011

” R for Business Analytics

its going to be a more business analytics than a stats perspective ( I am a MBA /Mech Engineer)

and use cases would be business analytics cases. Do write to me if you need help doing some analytics in R (business use cases)- or want something featured. Big focus would be on GUI and easier analytics, using the Einsteinian principle to make things as simple as possible but no simpler)

Message from RATTLE

A new release of the R GUI Rattle is making its way to CRAN (currently on the Austrian server).

Latest version 2.5.47 (revision 527) released 13 Nov 2010.

Change Log link for details -

http://cran.r-project.org/web/packages/rattle/index.html

Major changes relate to simplifying the installation of Rattle under the recently released R 2.12.0 on Microsoft Windows 32bit and 64bit.

The major advance for R 2.12.0 is the improved support for 64bit Microsoft Windows and thus support for much larger datasets in memory.

See the new installation steps at http://datamining.togaware.com/survivor/Internet_Connected.html

For Microsoft Windows installations, to upgrade your Rattle installation you may need to remove any old installs of the Gtk+ libraries using the Uninstall application from the Microsoft Windows Control Panel). Then install the new Gtk2 library:

http://downloads.sourceforge.net/gtk-win/gtk2-runtime-2.22.0-2010-10-21-ash.exe

You can the update Rattle to version 2.5.47:

> install.packages(“rattle“)

>library(rattle)

rattle.info()

The output from rattle.info() will include an “install.packages” command that will identify Rattle related packages that have updates available. You can cut-and-paste that command to the R prompt to have those packages updated in your installation.

Using R for Time Series in SAS

 

Time series: random data plus trend, with best...

Image via Wikipedia

 

Here is a great paper on using Time Series in R, and it specifically allows you to use just R output in Base SAS.

SAS Code

/* three methods: */

/* 1. Call R directly – Some errors are not reported to log */

x “’C:\Program Files\R\R-2.12.0\bin\r.exe’–no-save –no-restore <“”&rsourcepath\tsdiag.r””>””&rsourcepath\tsdiag.out”””;

/* include the R log in the SAS log */7data _null_;

infile “&rsourcepath\tsdiag.out”;

file log;

input;

put ’R LOG: ’ _infile_;

run;

/* include the image in the sas output.Specify a file if you are not using autogenerated html output */

ods html;

data _null_;

file print;

put “<IMG SRC=’” “&rsourcepath\plot.png” “’ border=’0’>”;

put “<IMG SRC=’” “&rsourcepath\acf.png” “’ border=’0’>”;

put “<IMG SRC=’” “&rsourcepath\pacf.png” “’ border=’0’>”;

put “<IMG SRC=’” “&rsourcepath\spect.png” “’ border=’0’>”;

put “<IMG SRC=’” “&rsourcepath\fcst.png” “’ border=’0’>”;

run;

ods html close;

The R code to create a time series plot is quite elegant though-


library(tseries)

air <- AirPassengers #Datasetname

ts.plot(air)

acf(air)

pacf(air)

plot(decompose(air))

air.fit <- arima(air,order=c(0,1,1), seasonal=list(order=c(0,1,1), period=12) #The ARIMA Model Based on PACF and ACF Graphs

tsdiag(air.fit)

library(forecast)

air.forecast <- forecast(air.fit)

plot.forecast(air.forecast)

Unbreakable Oracle Linux- and Unshakable-Libre Office-

Tux, the Linux penguin

Oracle announced Unbreakable Oracle Linux (which is the first time I have seen Unbreakable word used in a formal software name)- Hats off to good ol’ Larry chutzpah. It is also quite a fast form of Linux for Enterprises-as the stats say at http://www.oracle.com/us/technologies/linux/ubreakable-enterprise-kernel-linux-173350.html

LibreOffice is a new fork from OpenOffice- Basically people who want to ensure OpenOffice remains free. It basically consists of efforts from everybody except Apple, Microsoft and Oracle (http://www.documentfoundation.org/supporters/) and it’s a new kind of workable office productivity suite-determined to remain free. I have used it- a bit shaky- but I really liked the new design and willingly will test it (and auto submit bugs) . It would be interesting to see the reaction of enterprise vendors like SAS, IBM,Dell, HP (and Lenovo)  and etc -as their support would be critical to both Unbreakable Oracle Linux and Unshakable LibreOffice.

Blog Update

Some changes at Decisionstats-

1) We are back at Decisionstats.com and Decisionstats.wordpress.com will point to that as well. The SEO effects would be interesting and so would be the Instant Pagerank or LinkRank or whatever Coffee/Percolator they use in Cali to index the site.

2) AsterData is no longer a sponsor- but Predictive Analytics Conference is. Welcome PAWS! I have been a blog partner to PAWS ever since it began- and it’s a great marketing fit. Expect to see a lot of exclusive content and interviews from great speakers at PAWS.

3) The Feedblitz newsletter (now at 404 subscribers) is now a weekly subscription to send one big big email rather than lots of email through the week- this is because my blogging frequency is moving up as I collect material for a new book on business analytics that I would probably release in 2011 (if all goes well, touchwood). Linkedin group would be getting a weekly update announcement. If you are connected to Decisionstats on Analyticbridge _ I would soon try to find a way to update the whole post automatically using RSS and Ning.com . or not. Depends.

4) R continues to be a bigger focus. So will SPSS and maybe JMP. Newer softwares or older softwares that change more rapidly would get more coverage. Generally a particular software is covered if it has newer features, or an interesting techie conference, or it gets sued.

5) I will occasionally write a poem or post a video once a week randomly to prove geeks and nerds and analysts can have fun (much more fun actually dont we)

Thanks for reading this. Sept 2010 was the best ever for Decisionstats.com – we crossed 15,000 + visitors and thanks for that again! I promise to bore you less and less as we grow old together on the blog ;)

    refreshing of the Data tab.

  * Fix a bug in box plots when trying to label outliers when there aren't
    any.

And a video I did of exploring various Rattle options using Camtasia,
 a very useful software for screen capture and video tutorials
from http://www.techsmith.com/download/camtasiatrial.asp
Updated- my video skils being quite bad- I replaced it with another video. 
However Camtasia is the best screen capture video tool

Also , an update Analyticdroid is on hold for now.
see- for more details http://rattle.togaware.com/
