Add a label to a figure
The main purpose of this function is to add labels specifying extra information about
the figure, such as "Figure 1", or "A" - often useful in cowplots with more than
one pane. The function is similar to draw_plot_label.

label,
position = c("top.left", "top", "top.right", "bottom.left", "bottom", "bottom.right"),
size,
fontface,
...
)label |
