Annotate figures including: i) ggplots, ii) arranged ggplots from
ggarrange(), grid.arrange() and
plot_grid().
Usage
annotate_figure(
p,
top = NULL,
bottom = NULL,
left = NULL,
right = NULL,
fig.lab = NULL,
fig.lab.pos = c("top.left", "top", "top.right", "bottom.left", "bottom",
"bottom.right"),
fig.lab.size,
fig.lab.face
)Arguments
- p
(arranged) ggplots.
- top, bottom, left, right
optional string, or grob.
- fig.lab
figure label (e.g.: "Figure 1").
- fig.lab.pos
position of the figure label, can be one of "top.left", "top", "top.right", "bottom.left", "bottom", "bottom.right". Default is "top.left".
- fig.lab.size
optional size of the figure label.
- fig.lab.face
optional font face of the figure label. Allowed values include: "plain", "bold", "italic", "bold.italic".
