When presenting data on a plot, it is sometimes useful to also show a table with the actual numbers next to the plot. In some cases (e.g., mean profile plots and forest plots), the x-axes or y-axes of the individual plots/tables need to align with each other. There are several methods in combine plots and…
The function geom_text() can be used to annotate on graphs in GGplot2. Geom_text() uses data frames to annotate. Other functions such as annotate() can also be used to annotate in GGplot2. The annotate() function is described in this other post. The dataset The following dataset is used below to illustrate how to annotate on a…
Functions such as annotate() and geom_text() can be used to annotate a graph in GGPLOT2. This article focuses on the annotate() function which uses data passed in as vectors. The geom_text() function, which uses data frames, is covered in another article. The following example is based on the iris dataset which is available in R….
