Swivel is a website where people share reports of charts and numbers. Swivel is free for public data, and charges a monthly fee to people who want to use it in private.
For novices, functions are one of the most intimidating features of OpenOffice.org's Calc. Newcomers quickly learn that functions are a main feature of spreadsheets, but there are almost four hundred, and many require input that assume specialized knowledge. Nor are the often circular definitions of the Function Wizard much help: You are no better off for reading that the SKEW function "returns the skewness of a distribution," for example. However, Calc includes dozens of functions that anyone can use, the most basic of which create formulas for basic arithmetic or for evaluating numbers in a range of cells.
Given a directory on a drive, and a minimum and maximum file size, this program will graph the frequency with which files within that size range appear in that directory (and all subdirectories). See screenshot.

Hal Varian, Google’s Chief Economist, was interviewed a few months ago, and said the following in the McKinsey Quarterly: “The sexy job in the next ten years will be statisticians… The ability to take data—to be able to understand it, to process it, to extract value from it, to visualize it, to communicate it—that’s going to be a hugely important skill.”
Last week, Sam explored trends in the technology jobs market, suggesting that significant opportunities only reveal themselves when examining both the available jobs and the underlying trends in demand for skills. Coincidentally, on the same day that Sam’s piece was published, The New York Times suggested that “the sexy job in the next 10 years will be statisticians.”
With Open Source now considered an accepted part of the software industry, some people are starting to wonder if we can't bring the same degree of openness and innovation into government. Danese Cooper, who is actively involved in the open source community through her work with the Open Source Initiative and Apache, as well as working as an R wonk for Revolution Computing, would love to see the government become more open. Part of that openness is being able to access and interpret the mass of data that the government collects, something Cooper thinks R would be a great tool for. She'll be talking about R and Open Government at OSCON, the O'Reilly Open Source Convention.
REvolution Computing offers REvolution R, an enhanced distribution of R, as a free download. It also offers REvolution R Enterprise, a subscription-based version of R aimed at large companies that work with large data sets, and ParallelR (included in the Enterprise edition), which can take advantage of multi-processor systems and clusters for large data crunching tasks. R itself, and REvolution's versions, are being embraced in a number of fields, with a number of innovative new applications arriving.
FreeMat is a free environment for rapid engineering and scientific prototyping and data processing. It is similar to commercial systems such as MATLAB from Mathworks, and IDL from Research Systems, but is Open Source. FreeMat is available under the GPL license.
R Commander is a GUI for the R programming language, licensed under the GNU General Public License. Among the existing R GUIs, Rcmdr together with its plug-ins is perhaps the more viable R-alternative to commercial statistical packages like SPSS. The package is highly useful to R novices, since for each analysis run it displays the underlying R code.
Description: RKWard aims to provide an easily extensible, easy to use IDE/GUI for the R-project. RKWard strives to combine the power of the R-language with the (relative) ease of use of commercial statistical packages. While RKWard is far from finished, it is already useful to R experts looking for an IDE interface to the R language. For R novices, it provides graphical dialogs for a limited but growing number of statistical and graphing features.
Data presentation can be beautiful, elegant and descriptive. There is a variety of conventional ways to visualize data - tables, histograms, pie charts and bar graphs are being used every day, in every project and on every possible occasion. However, to convey a message to your readers effectively, sometimes you need more than just a simple pie chart of your results. In fact, there are much better, profound, creative and absolutely fascinating ways to visualize data. Many of them might become ubiquitous in the next few years.
