Web Development with R – an HD video tutorial of Jeroen Ooms talk

Here is a HD version of a video tutorial on web development with R, a lecture that was given by Jeroen Ooms (the guy who made A web application for R’s ggplot2). This talk was given at the Bay Area UseR Group meeting on R-Powered Web Apps.

You can also view the slides for his talk and view (great) examples for: stockplotlme4, and gpplot2.

Thanks again to Jeroen for sharing his knowledge and experience!

A web application for R's ggplot2

One of the exciting new frontiers for R programming is of creating website interfaces to R code. At the forefront of this domain is a young and (very) bright man called Jeroen Ooms, whom I had the pleasure of meeting at useR 2009 (press the link to see his presentation).

Today Jeroen announced a new version (0.11) of his web interface to ggplot2. See it here:

As Jeroen wrote:

New features include 1D geom’s (histogram, density, freqpoly), syntax mode (by clicking the tiny arrow at the bottom), and some additional facet options. And some minor improvements and fixes, most notably for Internet Explorer.
The data upload has not been improved yet, I am working on that. For now, it supports .csv, .sav (spss), and tab delimited data. Please make sure your filename has the appropriate extension and every column has a header in your data. If you export a dataframe from R, use:
write.csv(mydf, ”mydf.csv” , row.names=F). If you upload an spss
datafile, none of this should be a concern.
Supported browsers are IE6-8, FF, Safari, and Chrome, but a recent browser is highly recommended. As always, feedback is more than welcome.

Here is a little demo video that shows how to use the new features:

The datafile from the demo is available at http://www.yeroon.net/ggplot2/myMovies.csv.

I wish the best to Jeroen, and hope to see many more such uses in the future.
