Starting in February, Tog will be hosting a monthly open-source evening on the 3rd Wednesday of the month. These hands-on sessions aim to bring together experienced open-source contributors with people who would like to get started but aren’t sure where to start or would generally benefit from having someone to ask questions to. All types of contributions welcome: documentation, code, testing, artwork, translations…

For the first event, we have confirmed participants with varied levels of experience in Gnome, OpenStack, Django, OpenLDAP, OpenWonderland, the P2P django project, AppInventor*. If you’re an experienced contributor interested in attending, feel free to get in touch and get your project(s) added to the list. If you’re an aspiring contributor interested in attending, you can drop me a note too with the projects you’re planning on looking at during the evening.

If the project you’re interested in isn’t mentioned, please come anyway. We can figure out how a project works together. Likewise, people are welcome to come and work on their usual open-source stuff – just be open to the occasional question 🙂 The more people, the merrier!

The first event will be held on Wednesday, February 20th, with Tog opening at 6:30pm and the first talk starting at 7pm.

Every month we will start with a couple of people speaking for 5-10 minutes, to introduce the project they are working on, what is the usual path for contributing and where they are currently looking for help. Then we will form groups and work on making a contribution for the rest of the evening.

* (We have lost a few projects due to the flu – although it’s unfortunate, if you’re interested you can still get in touch with the person who was willing to help)

ggplot2 is the renowned R package used for high quality data visualization.

ggplot2 simplifies many of the details of creating statistical graphics while using the power of the underlying R graphics system to ensure those graphics are both beautiful and meaningful. The class will focus on how to produce many commonly used graphical procedures (histograms, scatterplots, bar charts), and how to enhance those plots according to the user’s wishes.

Attendees will require some basic knowledge of R (i.e. getting your data into R), but ggplot2 is a mini-language specifically tailored for producing graphics, and that will be the focus of the class. (See syntax example.) This workshop is run in conjunction with Dublin R.

When? Tuesday,  October 23rd from 19:30 till 21:30
Cost: €5 for non-members, free for members

Once again, the last R workshop turned out to be very popular and Kevin kindly agreed to teach another one! If you missed out on the last one, here’s your chance.

Since its inception, R has become one of the preeminent programs for statistical computing and data analysis. The ready availability of R, along with a wide variety of associated packages, marks it as an excellent choice for a multitude of computing tasks related to statistics and data science.

The workshop will introduce delegates to computing in the R environment; including data objects, basic calculations and using help, then progressing to some of the core features of R: vectorization, subscripting, and the some of the functions in R that are provided for common data management tasks.

As the workshop is intended to complement forthcoming Coursera statistics classes, very little statistical knowledge is expected.

The class will also include a short presentation from a developer who uses R professionally.

When? Saturday, September 29th, from 10:30 till around 15:30 (with breaks!)
Cost: €8 for non-members, free for members

Please use the form below the cut to sign up. Updated to add: we’re full! You can still sign up to be added to the waiting list.
