Introduction to R, Statistical Computing - Portland Data Viz
CubeSpace [ *sniff* out of business 12 June 2009]

R, also called GNU S, is a strongly functional language and environment to statistically explore data sets and make many graphical displays of data.

R is widely used for statistical software development and data analysis. R is part of the GNU project, and its source code is freely available under the GNU General Public License, and pre-compiled binary versions are provided for various operating systems. R uses a command line interface, though several graphical user interfaces are available.

Ed Borasky will provide an introduction to R this Saturday at Cubespace from 11Am-3Pm. Please come prepared with a laptop and the requisite software (link to come soon). If you have any issues installing the software, or need help before the meeting, feel free to arrive at 10:30 Am.

Software Downloads Updated to get ready for the upcoming class. There will be a few more pages coming. The first will be on installing GGobi, and the second will be on CRAN Task Views.

Here's an abbreviated "Getting Started With GGobi" guide. Please try this stuff out and let me know where it's broken. I just ran through the Windows part and the "Testing on a Social Network Dataset" part and that much of it works. :)

I added a couple of links to articles on using GGobi with social network data.

About R

R was created by Ross Ihaka and Robert Gentleman at the University of Auckland, New Zealand, and is now developed by the R Development Core Team. It is named partly after the first names of the first two R authors (Robert Gentleman and Ross Ihaka), and partly as a play on the name of S. The R language has become a de facto standard among statisticians for the development of statistical software.

Quantified Self Show & Tell: Analyzing Your Data

July's theme is: ANALYZING YOUR DATA

As QSers, we generate data like crazy, but many of us don't know what to do with it from there.

At this meetup, we're going to talk about what to do once you have data. If you have some data that you have worked through, I encourage you to come share the process with us so that we can all learn!

We'll also have a person or two from the Portland Data Science Group there to give us some analysis tips from the experts.

Here's our agenda:
Informal Social and Gadget Time - Starting at 6pm
Come early to socialize with other QSers and share what hardware, apps, and other technologies are helping you track your life. Bring your gadgets so that we can all see them, play with them, and hear your experiences with them!

Intro and Announcements - 6:30 sharp!

Show and Tell
Just like when you were in kindergarten, we encourage you to share something within the theme of the meetup. It doesn't a formal presentation, and can be as much as 10 minutes or as short as you like. Let us know in advance to guarantee your slot.

Portland Accessibility and User Experience Meetup (PDX A11Y UX) - Senses Working Overtime: Equivalent experiences in data viz for accessibility

Curious about how to make rich data visualizations accessible? Doug Schepers will share some of his work on how to create equivalent data viz experiences.

Images, charts, and diagrams are an important part of the web, but often hide critical information from people with disabilities of vision, cognition, and others. But there are many ways to provide inclusive affordances that use other senses, especially hearing and touch, to convey complex information. This talk will explore some of the challenges and different methods to overcome them using advanced techniques like text equivalents, sonification, haptics and tactiles, and more.

Event begins at 6:00pm; join early starting at 5:45pm for networking.

Online/call-in meeting info will be announced on Meetup.


  • 5:45–6:00pm Networking
  • 6:00–6:15pm Introductions & announcements
  • 6:15-7:00pm Presentations
  • 7:00–7:30pm Q&A and discussion
  • 7:30–7:45pm Wrap up

Accommodation requests:

If you have any accommodation requests, please contact us in advance of the event to discuss.

About the presenter:

Doug Schepers is the founder and director of Fizz Studio, an accessible data visualization startup in Chapel Hill, NC, USA. He develop his ideas and early prototypes for accessible charts while working with the accessibility community at W3C. As a developer who defined Web technologies and standards at W3C for a decade, he launched or worked on fundamental projects such as SVG (and the Accessible SVG Task Force), WebApps, Web Audio API, Touch Events and Pointer Events, Web Annotations, and many other technologies, as well as starting the W3C developer relations program.
