How to Make Grouped Violinplot with jittered data points in R
In this post, we will learn how to make grouped violin plot with jittered data points on top of it using ggplot2 in R. One of the challenges in making grouped violin or box plots with jittered data points is proper alignment of data points and the underlying plot. In an earlier tutorial, we addressed… Continue reading How to Make Grouped Violinplot with jittered data points in R
How to Make Barplots with rounded edges in ggplot
In this tutorial, we will learn how make bar plots with rounded edges in ggplot. We will use ggplot2 extension package called ggchicklet developed by the fantastic R developer boB Rudis/hrbrmstr. Let us get started by installing ggchicklet and loading tidyverse. We have installed ggchicklet version 0.5.2. Let us quickly generate data for making a… Continue reading How to Make Barplots with rounded edges in ggplot
Visualizing Binomial Distribution in R
In this tutorial, we will learn how to visualize binomial distribution in R. Binomial Distribution is one of the useful discrete probability distributions that comes handy in modelling problems in a number of scenarios. The classic example of binomial distribution is tossing a coin n times and counting the number of heads (successes) for a… Continue reading Visualizing Binomial Distribution in R
How to add water mark on a ggplot
In this tutorial, we will learn how to add water marks to a plot made in R. We will use ggplot2 to make the plot and use the R package cowplot to add water mark on top the plot. The cowplot package developed by Claus Wilke functions to draw with and on plots. These functions… Continue reading How to add water mark on a ggplot
