Feed: The Information Lab. Author: Chris Love. 19 January, 2020 Creating UpSet Plots in Tableau Authored by Chris Love. Feel free to chat on Twitter @chrisluv. Looking through #MakeoverMonday I noticed a couple of Venn Diagrams this week. Venn diagrams are very popular, and audiences will be familiar with them, but are difficult to build in Tableau. What is more there are some great alternatives – especially when trying to build plots with more than 3 combination states. UpSet Plots UpSet plots are a great alternative to a Venn. While they may require some explaining to an audience they can ... Read More

Yet another offshoot from my Advent of Code 2019 adventures (first half, second half, all solutions): on day 24, the challenge was to program a variant of Conway’s game of life, and I figured I might as well try my approach on the real thing! A quick google for existing implementations yields three main approaches: nested for, shifting of matrix rows and columns, and repeated filtering of a coordinate data.frame. Visualisations tend to rely on R’s plotting capabilities, and more recently {gganimate}. I used data.table for the computations, because it’s fast and succinct. Here’s ... Read More

Feed: AnalyzeCore by Sergey Bryl' – data is beautiful, data is a story. This is a guest blog post of my good friend Sergii Makarevych who has vast experience in Kaggle competitions and real-life data science projects implementation. There are some very important differences between a Kaggle competition and real-life project which beginner Data Scientists should know about. Kaggle creates a fantastic competition spirit. Its leaderboard drives people to deliver better and better solutions pushing accuracy to the limit. Kaggle’s Notebooks and Discussions make it easy to share knowledge and learn. However real-life projects are somewhat different. I hope this article ... Read More

Feed: R-bloggers. Author: Martin Chan. Background In an earlier post April this year, I discussed using flexdashboard (with RMarkdown) as an appealing and practical R alternative to Excel-based reporting dashboards. Since it’s possible to (i) export these ‘flexdashboards’ as static HTML files that can be opened on practically any computer (virtually no dependencies), (ii) shared as attachments over emails, and (iii) run without relying on servers and Internet access, they rival ‘traditional’ Excel dashboards on portability. This is an advantage that you don’t really get with other dashboarding solutions such as Tableau and Shiny, as far as I’m aware. Traditionally, ... Read More

Feed: Domo Blog. Author: Kevin McIsaac. It’s no secret that transformation is risky. For many, this risk outweighs the benefits of inactivity; McKinsey found that the rate of successful digital transformation is consistently low, with only 16% finding success over the long term. Within industries and business sizes, this also varies. Businesses with fewer than 100 employees are almost three times more likely to have fruitful transformational efforts compared to businesses with up to 50,000 employees. For those on the larger end of town, not only is the undertaking significantly more challenging, it is risky enough to see their business ... Read More

Inset maps enable multiple places to be shown in the same geographic data visualisation, as described in the Inset maps section (8.2.7) of our open source book Geocomputation with R.The topic of inset maps has gained attention and recently Enrico Spinielli asked inset maps could be created for data in unusual coordinate systems: Speaking of insets, do you know of any ggplot2 examples with an inset for showing where the (bbox of the) map is in an orthographic/satellite proj? It is usually done to provide geographic context… NYT/WP have fantastic maps like ... Read More
