Data visualisation using R, for researchers who don’t use R💯

Added Fri Feb 18th, 2022

What is this?

Excerpt from site: In this tutorial, we provide a practical introduction to data visualisation using R, specifically aimed at researchers who have little to no prior experience of using R. First we detail the rationale for using R for data visualisation and introduce the “grammar of graphics” that underlies data visualisation using the ggplot2 package. The tutorial then walks the reader through how to replicate plots that are commonly available in point-and-click software such as histograms and boxplots, as well as showing how the code for these “basic” plots can be easily extended to less commonly available options such as violin-boxplots.

geomtextpath

By Allan Cameron

Added Sat Dec 11th, 2021

What is this?

Excerpt from site: “The existing text-based geom layers in ggplot2 (geom_text and geom_label) are ideal for the majority of plots, since typically textual annotations are short, straight and in line with the axes of the plot. However, there are some occasions when it is useful to have text follow a curved path. This may be to create or recreate a specific visual effect, or it may be to label a circular / polar plot in a more”natural” way.”

How to pick more beautiful colors for your data visualizations💯 💯

By Lisa Charlotte Rost

What is this?

Excerpt from blog: Choosing good colors for your charts is hard. This article tries to make it easier.

I want you to feel more confident in your color choices. And if you have no sense for colors at all, here’s my attempt to help you find good ones anyway. We’ll talk about common color mistakes I see out there in the wild, and how to avoid them.

This is not the right article for you if you’re trying to find good gradients or shades. But if you need to find beautiful, distinctive colors for different categories (e.g. continents, industries, bird species) for your line charts, pie charts, stacked bar charts, etc., read on.

How to Increase Legend Key Size in ggplot2

By datavizpyr

Added Fri Apr 14th, 2023

What is this?

Excerpt from article: In this tutorial, we will learn how to increase the color legend’s point (or legend key) size in ggplot2. Often when you make a plot with multiple groups and large number of data points, the legend key for the color variable are small and can be not legible in the plot.

Here we will see examples of increasing the point size of the legend in a scatter plot using guides() function in ggplot2.

Improving ggplots with Text Color

By Eric Ekholm

Added Sun Jun 6th, 2021

What is this?

Excerpt from site: instead of having a legend off to the right or the bottom or wherever it is you typically place your legends, I’ve changed the font color of the words “Pass” and “Fail” in the title to contain this same information. We can do this using Claus Wilke’s invaluable {ggtext} package, which provides improved rendering for ggplot2.

Added Fri Apr 14th, 2023

What is this?

Excerpt from article: Here we describe a data visualization approach which overcomes these issues, providing maximal statistical information while preserving the desired ‘inference at a glance’ nature of barplots and other similar visualization devices. These “raincloud plots” can visualize raw data, probability density, and key summary statistics such as median, mean, and relevant confidence intervals in an appealing and flexible format with minimal redundancy. In this tutorial paper, we provide basic demonstrations of the strength of raincloud plots and similar approaches, outline potential modifications for their optimal use, and provide open-source code for their streamlined implementation in R, Python and Matlab (https://github.com/RainCloudPlots/RainCloudPlots).

TidyX YouTube channel hosted

By Ellis Hughes & Patrick Ward

What is this?

Excerpt from channel: TidyX is a screen cast where we select a person’s code from the TidyTuesday project and go through their code line-by-line, explaining what they did and how the functions they used work. We also break down the visualizations they create and talk about how to apply similar approaches to other data sets. The objective is to help more people learn R and get involved in the TidyTuesday community.
