Coordinate systems in ggplot2: easily overlooked and rather underrated

Lea Waniek Blog, Data Science, Statistik

All plots have coordinate systems. Perhaps because they are such an integral element of plots, they are easily overlooked. However, in ggplot2, there are several very useful options to customize the coordinate systems of plots, which we will not overlook but explore in this blog post. Since it is spring, we will use a random subset of the famous iris …

In the last post of this series, we took a first look at strategies for the effective visualization and exploration of data patterns within large data sets. Namely, we examined ways to overcome overplotting, with a focus on a two-dimensional feature space defined by two continuous features. However, oftentimes we want to visualize the distribution of data across several subgroups. …

Flowcharts of functions

Jakob Gepp Blog, Data Science

When you work on bigger R projects there comes a point when you may lose the overview of how your functions are connected. Or even worse: you get a large project and have to figure out what is actually happening! A possible remedy to this problem are flowcharts. If you started your project with a flowchart: good for you – …

.. oh what fun, it is to write, an R blog for this day! Der Grundgedanke von ggplot2 Das erklärte Ziel von Hadley Wickham’s package ggplot2, ist es R-Usern zu ermöglichen Daten einfach, ansprechend und vor allem informativ zu visualisieren. Dabei wurde angestrebt die Vorteile von sowohl base-R als auch dem älteren Package lattice zu übernehmen und deren Schwächen auszugleichen. …
