The grid R package can be used to create a complex layout with the help of the function grid.layout(). grid.arrange(bp, # bar plot spaning two columns The first row is all 1s, that’s where the first plot lives, spanning the two columns the second row contains plots 2 and 3 each occupying one column.

In the R code below layout_matrix is a 2x2 matrix (2 columns and 2 rows). It’s also possible to use the argument layout_matrix in the grid.arrange() function, to create a complex layout. Grid.arrange(sp, # First row with one plot spaning over 2 columnsĪrrangeGrob(bxp, dp, ncol = 2), # Second row with 2 plots in 2 different columns

the box plot (bxp) and the dot plot (dp) will live in the second row with two plots in two different columns.the scatter plot (sp) will live in the first row and spans over two columns.The function arrangeGrop() helps to change the row/column span of a plot. size: Font size of the label to be drawnįor example, you can combine multiple plots, with particular locations and different sizes, as follow: library("cowplot")ĭraw_plot(bxp, x = 0, y =.x, y: Vector containing the x and y position of the labels, respectively.draw_plot_label(label, x = 0, y = 1, size = 16. It can handle vectors of labels with associated coordinates. Adds a plot label to the upper left corner of a graph. width, height: the width and the height of the plotĭraw_plot_label().x, y: The x/y location of the lower left corner of the plot.plot: the plot to place (ggplot2 or a gtable).Places a plot somewhere onto the drawing canvas: draw_plot(plot, x = 0, y = 0, width = 1, height = 1) Note that, by default, coordinates run from 0 to 1, and the point (0, 0) is in the lower left corner of the canvas (see the figure below).ĭraw_plot(). Stat_cor(aes(color = cyl), label.x = 3) # Add correlation coefficient Shape = "cyl" # Change point shape by groups "cyl" Sp <- ggscatter(mtcars, x = "wt", y = "mpg",Ĭonf.int = TRUE, # Add confidence intervalĬolor = "cyl", palette = "jco", # Color by groups "cyl" X.text.angle = 90 # Rotate vertically x axis texts Sort.val = "asc", # Sort the value in ascending order

You’ll learn how to combine these plots in the next sections using specific functions.īxp <- ggboxplot(ToothGrowth, x = "dose", y = "len",ĭp <- ggdotplot(ToothGrowth, x = "dose", y = "len",Ĭolor = "dose", palette = "jco", binwidth = 1)

Bar plots and scatter plots using the mtcars data set.

Box plots and dot plots using the ToothGrowth data set.

We’ll start by creating 4 different plots: You can use any ggplot2 functions to create the plots that you want for arranging them later. Here, we’ll use ggplot2-based plotting functions available in ggpubr.
