Example 3: Manually Specify Filling Colors of ggplot2 Boxplot So far, we have only used thedefault color palette of the ggplot2 package. Example 3 explains how to add user-defined colors to our plot. For this task, we have to use the scale_fill_manual function as shown below: ggplot(d...
General color customization These for examples illustrate the most common color scales used in boxplot. Note the use of RcolorBrewer and viridis to automatically generate nice color palette. # library library(ggplot2) # The mtcars dataset is natively available in R #head(mpg) # Top Left: ...
