In Example 1, I’ll illustrate how to use the basic installation of the R programming language to plot several boxplots in the same graph. # values group Hello - I'm using the ALL dataset from the Bioconductor suite. You were passing two arguments that too with incorrect subsetting. In Example 2, I’ll illustrate how to use the functions of the ggplot2 package to add mean values to a boxplot in R. We first need to install and load the ggplot2 package, if we want to use the corresponding functions: install.packages("ggplot2") # Install & load ggplot2 package It's a shame this is not a native capability for R. ggplot2 is so common it might well be part of base R. You might want to have library(tidyverse) as the first command of any R session. The facet approach partitions a plot into a matrix of panels. I want a box plot of variable boxthis with respect to two factors f1 and f2.That is suppose both f1 and f2 are factor variables and each of them takes two values and boxthis is a continuous variable. In this example, we will use the function reorder() in base R to re-order the boxes. The function geom_boxplot() is used. row wise (i.e 1 row, 3 columns - all the figures are horizontally laid out) - mfrow=c(1,3), column wise (i.e 3 rows, 1 column - all the figures are vertically laid out) - mfrow=c(3,1), mix layout (i.e first two in top row, last in bottom - asymmetrical for 3) - mfrow=c(2,2). The base functionality has been expanded and made easier with ggplot2, part of the tidyverse of packages.In this chapter we will focus on examples using ggplot2, and we will occasionally suggest other packages. # Group.1 x data.frame(Ending_Average = c(0.275, 0.296, 0.259), Side-By-Side Boxplots.
