I like the visual appeal of commits by users over time at Github. For example, we can see Hadley Wickham is committed. But you already knew that. Nice to see a calender heat map being used effectively.
Now if we could only do that to CRAN (?) commits. Come on , Brian- you are not too old for this.
I got interviewed on moving on from Excel to R in Human Resources (HR) here at
“There is a lot of data out there and it’s stored in different formats. Spreadsheets have their uses but they’re limited in what they can do. The spreadsheet is bad when getting over 5000 or 10000 rows – it slows down. It’s just not designed for that. It was designed for much higher levels of interaction.
In the business world we really don’t need to know every row of data, we need to summarise it, we need to visualise it and put it into a powerpoint to show to colleagues or clients.”
And a more recent interview with my fellow IIML mate, and editor at Analytics India Magazine
AIM: Which R packages do you use the most and which ones are your favorites?
AO: I use R Commander and Rattle a lot, and I use the dependent packages. I use car for regression, and forecast for time series, and many packages for specific graphs. I have not mastered ggplot though but I do use it sometimes. Overall I am waiting for Hadley Wickham to come up with an updated book to his ecosystem of packages as they are very formidable, completely comprehensive and easy to use in my opinion, so much I can get by the occasional copy and paste code.
A surprising review at R- Bloggers.com /Intelligent Trading
The good news is that many of the large companies do not view R as a threat, but as a beneficial tool to assist their own software capabilities.
After assisting and helping R users navigate through the dense forest of various GUI interface choices (in order to get R up and running), Mr. Ohri continues to handhold users through step by step approaches (with detailed screen captures) to run R from various simple to more advanced platforms (e.g. CLOUD, EC2) in order to gather, explore, and process data, with detailed illustrations on how to use R’s powerful graphing capabilities on the back-end.

I really like the design, course structure and Hadley Wickham (in no particular order) as part of R Studio’ training suite which may be new, but is much better and open. Again I think Oracle’s training is awesome for online features , but some body needs to step up and create a credible R certification here. More power to R
Check it out-
For some time now, I had been hoping for a place where new package or algorithm developers get at least a fraction of the money that iPad or iPhone application developers get. Rapid Miner has taken the lead in establishing a marketplace for extensions. Is there going to be paid extensions as well- I hope so!!
This probably makes it the first “app” marketplace in open source and the second app marketplace in analytics after salesforce.com
It is hard work to think of new algols, and some of them can really be usefull.
Can we hope for #rstats marketplace where people downloading say ggplot3.0 atleast get a prompt to donate 99 cents per download to Hadley Wickham’s Amazon wishlist.
Do you think it is okay to pay 99 cents per iTunes song, but not pay a cent for open source software.
I dont know- but I am just a capitalist born in a country that was socialist for the first 13 years of my life. Congratulations once again to Rapid Miner for innovating and leading the way.
|RapidMiner, Marketplace, Extensions||30 May 2011|
|Rapid-I Marketplace Launched by Simon Fischer|
Over the years, many of you have been developing new RapidMiner Extensions dedicated to a broad set of topics. Whereas these extensions are easy to install in RapidMiner – just download and place them in the plugins folder – the hard part is to find them in the vastness that is the Internet. Extensions made by ourselves at Rapid-I, on the other hand, are distributed by the update server making them searchable and installable directly inside RapidMiner.
We thought that this was a bit unfair, so we decieded to open up the update server to the public, and not only this, we even gave it a new look and name. The Rapid-I Marketplace is available in beta mode at
. You can use the Web interface to browse, comment, and rate the extensions, and you can use the update functionality in RapidMiner by going to the preferences and entering http://rapidupdate.de:8180/UpdateServer/ as the update server URL. (Once the beta test is complete, we will change the port back to 80 so we won’t have any firewall problems.)
As an Extension developer, just register with the Marketplace and drop me an email (fischer at rapid-i dot com) so I can give you permissions to upload your own extension. Upload is simple provided you use the standard RapidMiner Extension build process and will boost visibility of your extension.
Looking forward to see many new extensions there soon!
Disclaimer- Decisionstats is a partner of Rapid Miner. I have been liking the software for a long long time, and recently agreed to partner with them just like I did with KXEN some years back, and with Predictive AnalyticsConference, and Aster Data until last year.
I still think Rapid Miner is a very very good software,and a globally created software after SAP.
Here is the actual marketplace
The Rapid-I Marketplace will soon replace the RapidMiner update server. Using this marketplace, you can share your RapidMiner extensions and make them available for download by the community of RapidMiner users. Currently, we are beta testing this server. If you want to use this server in RapidMiner, you must go to the preferences and enter
for the update url. After the beta test, we will change the port back to 80, which is currently occupied by the old update server. You can test the marketplace as a user (downloading extensions) and as an Extension developer. If you want to publish your extension here, please let us know via the contact form.
