Add brackets with custom p-value labels to a ggplot This section describes the functiongeom_bracket()[in ggpubr package] for adding brackets with label annotation to a ggplot. It makes it easy to add p-value or significance levels created elsewhere to a plot. Basic brackets with labels # ...
This post explains how to add labels on a circular barchart, on top of each bar. It uses R and ggplot2, and reproducible code is provided.
This example demonstrates how to annotate the number of observations per group as text labels to each box of a ggplot2 boxplot.To do this, we can apply the annotate function as shown below:ggp + # Add counts by group to boxplot annotate("text", x = 1:length(table(data$group)), y...
data <- data.frame(x = c(4, 1, 3, 3, 7, 2), # Create example data y = 1:6) data # Print example dataTable 1 shows the structure of our exemplifying data: It contains six rows and two columns.We also have to install and load the ggplot2 package, to be able to use the ...
The optionvjustis used to vertically adjust the position of the p-values labels Note that, in some situations, the p-value labels are partially hidden by the plot top border. In these cases, the ggplot2 functionscale_y_continuous(expand = expansion(mult = c(0, 0.1)))can be used toadd...
nudge_xandnudge_y: let you offset labels from their corresponding points. The functionposition_nudge() can be also used. check_overlap= TRUE: for avoiding overplotting of labels hjustandvjustcan now be character vectors (ggplot2 v >= 2.0.0): “left”, “center”, “right”, “bottom”...
