Interactive charts in R

I’m giving a talk tomorrow at the Edinburgh R usergroup (EdinbR) on how to get started building interactive charts in R. I’ll talk about rCharts as a great general entry point to quickly generating interactive charts, and also the newer htmlwidgets movement, allowing interactive charts to be more easily integrated with RMarkdown and Shiny. I also tried to throw in a decent amount of Edinburgh-related examples along the way.

Current slides are here:

I’ve since spun out what started as a simple example for the talk into a live web app, viewable at blackspot.org.uk. Here I’m looking at Edinburgh Open Data from the county council of vehicle collisions in the city. It’s still under development and will be my first real project in Shiny, but already has started to come together quite nicely.

The other speaker for the session is Alastair Kerr (head of bioinformatics at the Wellcome Trust Centre for Cell Biology here in Edinburgh), and he’ll be giving a beginner’s guide to the Shiny web framework. All in all it should be a great meeting, if you’re nearby do come along!

Planning an R usergroup meeting in R

The edinbr_logoEdinburgh R usergroup (EdinbR) put together a survey a while back to figure out some of the logistical details for organising a succesful meeting. We had 75 responses (and a few more after I grabbed the results) so here’s some quick analysis, all done in R of course. The code and data for these figures are available on the EdinbR github account.

Who’s coming to EdinbR meetings?

attendance

It looks like the majority of our audience would describe themselves as having an “intermediate” level of R knowledge, but there’s a good number of beginners too. The overall number of attendees is promising: 43 said they’d attend either every meeting or most meetings!

When’s the best time and day for meetings?

Together the results for the best time and day were potentially biased by our very first meeting (which happened at Wednesday 5pm)…

Regardless this result means we’ll stick with Wednesdays at 5pm for now, without prejudice against lunchtime sessions in the future.

Where should meetings be held?

venues

Again strong support for the status quo: George square (and Bristo square, informatics etc.) are nice, central locations which are ideal for those based in the city centre and a decent compromise for those further afield, such as EdinbR attendees from the IGMM or King’s Buildings.

What do we want to hear about?

The organisers had already put together a  very non-comprehensive list of potential topics for future meetings and so we asked respondents to select those they were interested in hearing about:

This gives a rough roadmap for upcoming EdinbR meetings: if you could give a talk about any of the above topics then do let us know; you can reach me by email or on twitter, and do join our mailing list to be notified of our next meeting!

EdinbR: A new R usergroup for Edinburgh

Inspired by succesful RUGs like LondonR and CambR, I’m pleased to announce a new R usergroup for those in and around Edinburgh: EdinbR!

edinbr_logo
Edinburgh has a large research community using R, spread across different campuses and even universities so a centralised discussion group is long overdue. Many R packages have been developed by Edinburgh researchers, ranging from general parallelisation packages (SPRINT) to highly-specific packages targetting cutting-edge genomics data (poRe). It seems like a great idea to get these people talking to each other: developers, users and interested newbies alike!

So without further ado, the details for our first meeting are:

  • Date: Wednesday 17:00 18th February 2015
  • Venue: Room S1, 7 George Square Psychology building, Edinburgh
  • Topics: Refining plans for meeting format, timing, venues; selecting speakers for future meetings; advertising meetings, etc.

All are welcome regardless of R experience. We hope to run a range of meetings with some aimed at general or beginner topics and others delving more deeply into advanced areas.

If you might be interested in attending, we have a mailing list where meetings will be advertised, we’re on twitter (@edinb_r) and you can email the organisers at info@edinbr.org.

We hope to see you there!
