geom_edgetext | R Documentation |
All arguments to both geom_edgetext
and
geom_edgelabel
are identical to those of
geom_label
, with the only difference that the
label.size
argument defaults to 0
in order to avoid drawing a
border around the edge labels. The labels will be drawn at mid-edges.
geom_text
and geom_label
produce strictly
identical results.

mapping |
Set of aesthetic mappings created by |
data |
The data to be displayed in this layer. There are three options: If A A |
position |
Position adjustment, either as a string, or the result of
a call to a position adjustment function. Cannot be jointly specified with
|
parse |
If |
... |
Other arguments passed on to |
nudge_x , nudge_y |
Horizontal and vertical adjustment to nudge labels by.
Useful for offsetting text from points, particularly on discrete scales.
Cannot be jointly specified with |
label.padding |
Amount of padding around label. Defaults to 0.25 lines. |
label.r |
Radius of rounded corners. Defaults to 0.15 lines. |
label.size |
Size of label border, in mm. |
na.rm |
If |
show.legend |
logical. Should this layer be included in the legends?
