In this post we will see an example of one of most common errors while making a plot with ggplot2 and how to fix them. Let us we are trying to make a scatter plot using ggplot2 using the following code. Here we use mtcars dataset built-in R to make the scatter plot If we… Continue reading Error in ggplot(): Mapping should be created with `aes()`

ggplot2 errot: how to fix could not find function “ggplot
In this post we will learn how to fix one of the most common ggplot2 errors, saying “could not find function “ggplot”” Let us consider an example where we are trying to make boxplot using iris, one of the R built-in datasets. We have been extra careful and write a perfect R code as show… Continue reading ggplot2 errot: how to fix could not find function “ggplot
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
Introduction: Understanding and Visualizing the Binomial Distribution in R The binomial distribution is one of the most common discrete probability distributions in statistics. It models the number of successes in n independent Bernoulli trials, each with the same probability of success p. The classic example of binomial distribution is tossing a coin n times and… Continue reading Visualizing Binomial Distribution in R
