GGobi

Hack-at-it 2010

2010-06-04T14:34:00.000-07:00

Members of the team met for the second time in 2010, to work on a new interactive graphics canvas for R. The current stage of the project can be found at R-forge: qtinterfaces contains the new canvas, and plumbr contains the new mutable data frame structures which will enable linking between plots.

The goal is to have working examples by the end of summer 2010.

Hack-at-it 2009

2009-06-09T07:12:00.000-07:00

The annual GGobi hack-at-it was held June 5-7 in Ames Iowa. The main directions of work are

Development of a new canvas for R supporting interactive and dynamic graphics. Michael is leading the effort on this. Higher level routines for supporting brushing and linking are progressing, and the design will follow the pipeline ideas expressed in the 2008 Computational Statistics paper.
A tourr package is coming along for running tours, of many varieties, and allowing experimentation with tours, directly in R. This will eventually be integrated with the new canvas to allow brushing on the tour projections. A GUI has also been developed.
A simple GUI for interactive mosaic plots in R has been developed.
Another package developing templates for composite plots, such as pairs plots for multivariate data containing different types of variables is coming along. This is inspired by Jay Emerson's gpairs function in the YaleToolkit.

2009 Chambers award winner announced

GGobi and Choreography

2009-04-12T11:38:00.001-07:00

You might be interested in this rather unusual use of GGobi - to explore and understand dance! Noel Cressie, Ola Ahlqvist, and Hyowon Ban from the Ohio State University have been involved in a collaborative project centred around a William Forsythe modern-dance piece called "One Flat Thing, reproduced. See their contribution, "Statistical counterpoint", and learn more about their work.

Updated version of GGobi: 2.1.8

2008-08-12T08:37:00.000-07:00

We've just posted an updated version of GGobi - version 2.1.8. This version fixes a number of small bugs, particularly with the
DescribeDisplay plugin. If you are on windows, make sure to also update to the latest version of gtk linked from the downloads page. Unfortunately we have been having problems with the mac package, so only linux and windows versions are currently available.

All files are available from http://ggobi.org/downloads

Please us know if you run into any problems.

GGobi in Wikipedia

2008-06-27T01:07:00.000-07:00

GGobi now has an entry in Wikipedia. Feel free to edit it!

Hack-at-it 2008

2008-06-27T00:57:00.000-07:00

The 2008 Hack-at-it was held June 22-23, just before Data Vis VI, in Bremen Germany.

The main topics for the meeting were:

Release of 2.1.7
Continued design of GGobi 3

New material on the GGobi book web page

2008-01-30T02:59:00.000-08:00

The GGobi book is now available from Springer and Amazon, after quite a delay. Getting the figures printed correctly was difficult.

Solutions to the exercises in the back of each chapter are available for instructors by emailing Springer.

The movies on the book web site are currently being updated to include sound.

Hack-at-it 2007

2008-01-28T02:25:00.000-08:00

The GGobi Hack-at-it 2007 was held just before useR! 2007 in Ames Iowa.

The main focus this year was on the data pipeline again, and on pipelines in other software.
Several projects were discussed: the geometric shapes, high-dimensional games, local neighborhood brushing, metabolomics data preprocessing.

The first business meeting of the GGobi Foundation was held, too, working on the by-laws, and other operating procedures.

Geometric shapes

2007-08-29T07:55:00.000-07:00

If you haven't seen them already, be sure to check out Barret Schloerke's geometric shapes. He's an undergrad student who's been working with us over summer to generate a variety of high-dimensional geometric shapes to explore with GGobi.

The data includes cubes, spheres, simplexes, polyhedra, polytopes, and mobius-like objects, ranging from from 3d
to 10d. For each object Barret has made a data set, image, short movie and the R code necessary to recreate the data.

GGobi 2.1.6

2007-08-20T19:27:00.000-07:00

Just a quick note to let you know that GGobi 2.1.6 has been released
and is available from Windows, Mac (with easy installer) and Linux
from http://www.ggobi.org/downloads. The changes are largely internal
with a few more bugs being fixed.

We are working on getting rggobi on to CRAN now, and we hope that it
will be available for all platforms within the next week. If you are
using rggobi, you might want to hold off on upgrading GGobi until
then.

Again, GGobi 2.1.6 is available from http://www.ggobi.org/downloads

Static and dynamic graphics course, July 2007, Salt Lake City

2007-03-05T06:56:00.000-08:00

We're pleased to announce a one day course covering static and dynamic graphics using R, ggplot and GGobi. The course will be held just before the JSM, on Saturday, 28 July 2007, in Salt Lake City. The course will be presented by Dianne Cook and Hadley Wickham.

In the course you will learn:

How to build presentation quality static graphics using the R package, ggplot. We will cover plot creation and modification, and discuss the grammar which underlies the package.

How to explore your data with direct manipulation/dynamic graphics using GGobi and rggobi. You'll learn the general toolbox, as well specific approaches for dealing with missing data, supervised classification, cluster analysis and multivariate longitudinal data analysis.

Dianne Cook is a full professor at Iowa State University. She has been an active researcher in the field of interactive and dynamic graphics for 16 years, and regularly teaches information visualization, multivariate analysis and data mining.

Hadley Wickham is a PhD student at Iowa State University. He won the John Chambers Award for statistical computing in 2006 for his work on ggplot.

Hack-at-it

2006-10-25T07:12:00.000-07:00

Hack-at-it 2006

Aug 3-5 the GGobi developers got together in Seattle, WA for the second hack-at-it. The setting was a rented house, with high speed internet and a lovely garden in which to work and talk.

The main topic of this year's hack-at-it was the ggobi pipeline. Plans were laid to restructure the backbone of the software to make it more extensible, and programmable from R. Most of this will be invisible to the user, but the results will be obvious in new graphics types and applications running from R.

GGobi 2.1.4 released

2006-10-23T07:51:00.000-07:00

We are pleased to announce the release of GGobi 2.1.4. This is another bug fix release, fixing a few annoying crasher bugs, as well some xml and linking bugs. It is available for download now from http://www.ggobi.org/downloads/.

This version offers improved compatibility with rggobi and we hope to release a new version of rggobi with many new features very soon. We are also working on an easy mac installer, which hopefully will be ready in the next couple of weeks.

If you do encounter any problems please email the mailing list - your feedback is appreciated.

New ggobi release

2006-08-29T11:19:00.000-07:00

GGobi

There is a new release of ggobi 2.1.3 available on the web site. It has few changes, but several bugs have been fixed. A more major release will happen later this year.

Describe Display

2006-07-13T12:26:00.000-07:00

Making good quality reproductions of ggobi plots

To create high quality reproductions of ggobi plot windows, take a look at the DescribeDisplay plugin and corresponding R package.

The R package is available at http://www.ggobi.org/describe-display/ .

The R package takes the R scripts describing the ggobi plots produced by the plugin and reproduces the plots in R. These can be saved as pdf or some other format for inclusion in papers. Actually most of the figures in the upcoming book on R and ggobi were produced this way.

rggobi 2.1.3 released (for linux and mac)

2006-04-02T11:24:00.000-07:00

This is bug fix for a problem that a number of users on the mac have
been experiencing.

If you have already successfully installed rggobi, you do not need to upgrade.

The new file is available from http://www.ggobi.org/downloads/

GGobi 2 official release
