PubMed Commons, the NCBI’s experiment in comments for PubMed articles, has been discontinued. Thoroughly too, with all traces of it expunged from the NCBI website.
Last time I wrote about the service, I concluded “all it needs now is more active users, more comments per user and a real API.” None of those things happened. Result: “NIH has decided that the low level of participation does not warrant continued investment in the project, particularly given the availability of other commenting venues.”
NLM also write that “all comments are archived on our FTP site.” A CSV file is available at this location. So is it good for anything?
You know the drill by now. Grab the tweets. Generate the report using RMarkdown. Push to Github. Publish the report.
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, the rtweet package went through a brief phase of returning lists instead of nice data frames. I hope that’s been discarded as a bad idea :) There also seem to be additional columns, new column names and list-columns in the output from the latest
search_tweets(), so there goes my previous code…
Second, given that most Twitter users have had 280 characters since about November 7, is this reflected in the conference tweets?
With thanks to Andrew Lonsdale for clearing up my confusion and pointing me to Twitter extended mode, the answer is “yes, somewhat”. Plenty of tweets are still hitting the 140 limit though: time to update those clients?
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 table containing Australian members of parliament, their electorate and their voting intention regarding legalisation of same-sex marriage. Since I reside in New South Wales, let’s map the data for electorates in that state.
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 takes up about 10 hours of my week, so I found it hard to justify two hours for one podcast, no matter how good.
Were the episodes really getting longer over time? Let’s find out using R.
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 a time. The realisation hits slowly: at some point you look around at the yellow-brown lawns, ovals and “nature strips” and say “gee, I don’t remember the last time it rained.”
Thankfully in our data-rich world, it’s relatively easy to find out whether the dry spell is really as long as it feels. In Australia, meteorological data is readily available via the Bureau of Meteorology (known as BoM). Another source is the Weather Underground (WU), which has the benefit that there may be data from a personal weather station much closer to you than the BoM stations.
Here’s how you can access WU data using R and see whether your fuzzy recollection is matched by reality.
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 has been called a waffle chart and for extra “infographic-i-ness”, the squares can be replaced by icons. You want to do this using R? Of course you do. Here’s how.
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 time – but I don’t think years as coloured bars is the way to go. To me, progression over time suggests that time should be an axis, so as the eye moves along the data from one end to the other, without interruption. What I want to see is categories over time, not time within categories.
So what is the way to go? Let’s ask “what would ggplot2 do?”
First there was “insert statistical method here“. Now we have R – making it easy “to do analysis stuff“.
Via Elisabeth; I’ll hand you over now for an entertaining summary.
To be fair, analysis stuff describes my working life quite well.

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 my bioinformatics career, but unfortunately the seed for the “no more southern hemisphere meetings” decision), and in Toronto 2008. The latter was notable for its online coverage and for me, the pleasure of finally meeting in person many members of the online bioinformatics community.
The 2017 meeting (and its satellite meetings) were covered quite extensively on Twitter. My search using a variety of hashtags based on “ismb”, “eccb”, “17” and “2017” retrieved 9052 tweets, which form the basis of this summary. Code and raw data can be found at Github.
Usually I just let these reports speak for themselves but in this case, I thought it was worth noting a few points:
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 for Twitter conference hashtags pulled out 3268 tweets and without further ado here is the Github repository, where you can view the markdown report in the
The ISMB/ECCB meeting wraps today and analysis of Twitter coverage for that meeting will appear here in due course.
