You know the drill by now. Grab the tweets. Generate the report using RMarkdown. Push to Github. Publish to RPubs. This time it’s the Australian Bioinformatics & Computational Biology Society Conference 2017, including the COMBINE symposium. Looks like a good time was had by all in Adelaide. A couple of quirks this time around. First, … Continue reading Twitter...

Mapping data using R and leaflet

The R language provides many different tools for creating maps and adding data to them. I’ve been using the leaflet package at work recently, so I thought I’d provide a short example here. Whilst searching for some data that might make a nice map, I came across this article at ABC News. It includes a … Continue reading Mapping...

XML parsing made easy: is that podcast getting longer?

Sometime in 2009, I began listening to a science podcast titled This Week in Virology, or TWiV for short. I thought it was pretty good and listened regularly up until sometime in 2016, when it seemed that most episodes were approaching two hours in duration. I listen to several podcasts when commuting to/from work, which … Continue reading XML...

Feels like a dry winter – but what does the data say?

A reminder that when idle queries pop into your head, the answer can often be found using R + online data. And a brief excursion into accessing the Weather Underground. One interesting aspect of Australian life, even in coastal urban areas like Sydney, is that sometimes it just stops raining. For weeks or months at … Continue reading Feels...

Infographic-style charts using the R waffle package

Infographics. I’ve seen good examples. I’ve seen more bad examples. In general, I prefer a good chart to an infographic. That said, there’s a “genre” of infographic that I do think is useful, which I’ll call “if X were 100 Y”. A good example: if the world were 100 people. That method of showing proportions … Continue reading Infographic-style...

Years as coloured bars

I keep seeing years represented by coloured bars. First it was that demographic tsunami chart. Then there are examples like the one on the right, which came up in a web search today. I even saw one (whispers) at work today. I get what they are trying to do – illustrate trends within categories over … Continue reading Years...

Twitter Coverage of the ISMB/ECCB Conference 2017

ISMB (Intelligent Systems for Molecular Biology – which sounds rather old-fashioned now, doesn’t it?) is the largest conference for bioinformatics and computational biology. It is held annually and, when in Europe, jointly with the European Conference on Computational Biology (ECCB). I’ve had the good fortune to attend twice: in Brisbane 2003 (very enjoyable early in … Continue reading Twitter...

Twitter Coverage of the Bioinformatics Open Source Conference 2017

July 21-22 saw the 18th incarnation of the Bioinformatics Open Source Conference, which generally precedes the ISMB meeting. I had the great pleasure of attending BOSC way back in 2003 and delivering a short presentation on Bioperl. I knew almost nothing in those days, but everyone was very kind and appreciative. My trusty R code … Continue reading Twitter...

Hacking Highcharter: observations per group in boxplots

Highcharts has long been a favourite visualisation library of mine, and I’ve written before about Highcharter, my preferred way to use Highcharts in R. Highcharter has a nice simple function, hcboxplot(), to generate boxplots. I recently generated some for a project at work and was asked: can we see how many observations make up the … Continue reading Hacking...

Chart golf: the “demographic tsunami”

“‘Demographic tsunami’ will keep Sydney, Melbourne property prices high” screams the headline. While the census showed Australia overall is aging, there’s been a noticeable lift in the number of people aged between 25 to 32. As the accompanying graph shows… Whoa, that is one ugly chart. First thought: let’s not be too hard on Fairfax … Continue reading Chart...
