When plotting data for different groups, one has different options to identify them, for example, by means of different colors or different shapes. However, with many groups, it often becomes very difficult or even impossible to discriminate between the groups. Herein, I will illustrate a solution to plot an intermediate number of groups with ggplot2. First, I will use different colors to discriminate between the groups. https://hansjoerg.me/2018/07/17/web-scraping-world-cup/ Tue, 17 Jul 2018 00:00:00 +0000 https://hansjoerg.me/2018/07/17/web-scraping-world-cup/ While watching a FIFA World Cup game, I suddenly had the impression that games got fairer over the years. Everybody remembers the headbutt of Zinedine Zidane, but I haven’t seen similar things in 2018. I always wanted to try out web scraping and this was the opportunity to do so. https://media.giphy.com/media/9AuHkzLy26AmI/giphy.gif In this post, I will give a very brief intro to web scraping focusing mostly on scraping the World Cup data.
