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 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
How to Reverse Order in Facet in ggplot
In this tutorial, we will learn how to reverse the order of facets, multiple small plots, made with ggplot2 in R. We will use R package forcats’s handy function fct_rev() to reverse the order of facets made using facet_wrap() function in ggplot2. Let us load tidyverse suite of R packages and palmer penguin dataset for… Continue reading How to Reverse Order in Facet in ggplot
How to Add Colors to Axis Tick Label in ggplot2
In this tutorial, we will learn how to add colors to axis tick labels in ggplot2. To add colors to axis labels we will use the R package “ggtext: Improved text rendering support for ggplot2” developed by Claus Wilke. Let us get started by loading the packages needed. We will use Palmer Penguin data set… Continue reading How to Add Colors to Axis Tick Label in ggplot2
