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.

We should probably try to clean that up a little; some of the other tags have put a lot of effort into it. (e.g. stackoverflow.com/tags/java/info)

@DirkEddelbuettel you catch Ajay’s latest? ow.ly/3a8gK
ha! yeah that would be good signaling. Not sure how common it is, but I use it mostly for spam bots. I actually have only blocked 2 warm blooded humans (counting Ajay’s multiple accts as one person)

speaking of shane’s mom, he and Josh deciding to be productive members of real society today?

Statistical Analysis with R- by John M Quick
I was asked to be a techie reviewe for John M Quick’s new R book “Statistical Analysis with R” from Packt Publishing some months ago-(very much to my surprise I confess)-
I agreed- and technical reviewer work does take time- its like being a mid wife and there is whole team trying to get the book to birth.
Statistical Analysis with R- is a Beginner’s Guide so has nice screenshots, simple case studies, and quizzes to check recall of student/ reader. I remember struggling with the official “beginner’s guide to R” so this one is different in that it presents a story of a Chinese Army and how to use R to plan resources to fight the battle. It’s recommended especially for undergraduate courses- R need not be an elitist language- and given my experience with Asian programming acumen – I am sure it is a matter of time before high schools in India teach basic R in final years ( I learnt quite a shit load of quantum physics as compulsory topics in Indian high schools- but I guess we didnt have Jersey Shore things to do)
Congrats to author Mr John M Quick- he is doing his educational Phd from ASU- and I am sure both he and his approach to making education simple informative and fun will go places.
Only bad thing- The Name Statistical Analysis with R has atleast three other books , but I guess Google will catch up to it.
This book is here-https://www.packtpub.com/statistical-analysis-with-r-beginners-guide/book

Amazon goes HPC and GPU: Dirk E to revise his R HPC book
Amazon just did a cluster Christmas present for us tech geek lizards- before Google could out doogle them with end of the Betas (cough- its on NDA)
Clusters used by Academic Departments now have a great chance to reduce cost without downsizing- but only if the CIO gets the email.
While Professor Goodnight of SAS / North Carolina University is still playing time sharing versus mind sharing games with analytical birdies – his 70 mill server farm set in Feb last is about to get ready
( I heard they got public subsidies for environment- but thats historic for SAS– taking public things private -right Prof as SAS itself began as a publicly funded project. and that was in the 1960s and they didnt even have no lobbyists as well. )
In realted R news, Dirk E has been thinking of a R HPC book without paying attention to Amazon but would now have to include Amazon
(he has been thinking of writing that book for 5 years, but hey he’s got a day job, consulting gigs with revo, photo ops at Google, a blog, packages to maintain without binaries, Dirk E we await thy book with bated holes.
Whos Dirk E – well http://dirk.eddelbuettel.com/ is like the Terminator of R project (in terms of unpronounceable surnames)
Back to the cause du jeure-
From http://aws.amazon.com/ec2/hpc-applications/ but minus corporate buzz words.
Unique to Cluster Compute and Cluster GPU instances is the ability to group them into clusters of instances for use with HPC
applications. This is particularly valuable for those applications that rely on protocols like Message Passing Interface (MPI) for tightly coupled inter-node communication.
Cluster Compute and Cluster GPU instances function just like other Amazon EC2 instances but also offer the following features for optimal performance with HPC applications:
- When run as a cluster of instances, they provide low latency, full bisection 10 Gbps bandwidth between instances. Cluster sizes up through and above 128 instances are supported.
- Cluster Compute and Cluster GPU instances include the specific processor architecture in their definition to allow developers to tune their applications by compiling applications for that specific processor architecture in order to achieve optimal performance.
The Cluster Compute instance family currently contains a single instance type, the Cluster Compute Quadruple Extra Large with the following specifications:
23 GB of memory
33.5 EC2 Compute Units (2 x Intel Xeon X5570, quad-core “Nehalem” architecture)
1690 GB of instance storage
64-bit platform
I/O Performance: Very High (10 Gigabit Ethernet)
API name: cc1.4xlarge
