You can plot this type of graph from different inputs, like vectors or data frames, as we will review in the following subsections. This R tutorial describes how to create a box plot using R software and ggplot2 package.. In base R, we use boxplot function to create the boxplots but if we have categorical vector and the corresponding numerical vector then the boxplot can be easily created. Group A and C are represented using a similar way: same color, and same ‘b’ letter on top. The basic syntax to create a boxplot in R is − boxplot(x, data, notch, varwidth, names, main) Following is the description of the parameters used − x is a vector or a formula. R Boxplot Multiple Columns R Boxplot Multiple Columns When we want to study patterns collectively rather than individually, individual values need to be categorized into a number of groups beforehand. You will also learn to draw multiple boxplots in a single plot. Here, we’ll use the R built-in ToothGrowth data set. This is the tenth tutorial in a series on using ggplot2 I am creating with Mauricio Vargas Sepúlveda.In this tutorial we will demonstrate some of the many options the ggplot2 package has for creating and customising boxplots.

I am not looking to use additional packages (such as ggplot) - I am trying to do this through just the R core. To use this parameter, you need to supply a vector argument with two elements: the number of rows and the number of columns. For instance, when running an ANOVA on multiple groups in a search for possible differences, creating a multiple boxplot would strongly help you visualizing the spread of each of the groups and to the apparent differences between them. You can also pass in a list (or data frame) with … How to create boxplot for multiple categories in base R?
