Setting up twitter streamR Service on an Ubuntu server

I am working on a super-secret project for which I am harvesting a highly confidential source of data: twitter ? The idea is to gather a small amount of twitter data, but for a long time… maybe a year. I tried to use the package TwitteR, but it can only  grab up to a week of tweets… it’s not...

Announcing ShinyTester – a package that helps you build Shiny apps

Shiny is awesome, but can be a bit daunting and easy to make mistakes in. I recently came back to Shiny after a hiatus of a few years and it was much more challenging than I feel comfortable admitting. I was making bonehead mistakes like writing something instead of output$something, confusing where to put Output commands vs Render commands, etc. I...

Pop quiz! What is this chart saying?

I have been reading more and more about how people can’t interpret charts… which kinda never occurred to me, if I’m gonna be very honest.  Anyway, it kind of made me think of actually testing people informally, to see for myself. So I’ve been doing just that: showing colleagues, friends, etc a chart that we created interactively during the first...

Heart-shaped wordcloud, celebrating Colombia peace treaty

This is a lightening quick post just providing the script to draw a heart-shaped wordcloud, using the awesome wordcloud2 package. See the resulting image here:   Apparently, the original code allows you to fit a wordcloud to any shape, even custom shapes, but I didn’t find that functionality pushed out into R yet (a peace sign would have been...

Track your local R scheduled tasks with CommandCenter2000!!!

There are many ways to automate your scripts running, for example using RScript, or in-R itself (and now even as an add-in for RStudio) (check all here). But after a while, it can get a bit overwhelming to track tasks and ensure they are firing as planned. In order to address this, I have developed some futuristic advanced tech that lets...

I’m leading the Accra R-User Meetups!

May 24, 2016

I am not sure how, but I found Data Science Africa, whose mission it is to promote data science in Africa. For now, they are limited to organizing and running meetups across Africa, mostly focused on R, although there are higher albeit more ambitious targets. Anyway, since I’m in Accra, I contacted them to see if I could help...

Make dashboard Tiles/Notecards in R

Dashboard Tiles/Notecards are a great way to visualize just one number, and make it big and pretty. They can emphasize results in an easily digestible and colourful format. I was surprised that there was no way to create tiles offline (there is however a very good online version in shinydashboards), so …

KPI dashboard in R with animated icons

So Key Performance Indicators (KPIs) are all the rage in the dashboarding community… well everywhere really. The premise is simple… check a list of measurements against targets and show how they compare using some kind of visualization. I haven’t yet seen, however, a version that can utilize animated icons to display …

R Tagosphere!

This post explores the inter-relationships of StackOverflow Tags for R-related questions. So I grabbed all the questions tagged with “r”, took the other tags in each question and made some network charts that show how often each tag is seen with the other tags. The point is to see the empirical relationships …

Clickable list of the best animations since 1900, gathered the geek way.

In the midst of our random data exploration, Laure and I started playing around with Hadley’s movies dataset and noticed that there were a lot of old cartoon animations… I mean REALLY old. So we got excited and wondered if we could find Youtube links for all these old animations. Indeed we could! …
