geom_nodetext | R Documentation |
All arguments to these geoms are identical to those of
geom_text
and geom_label
.
geom_nodetext( mapping = NULL, data = NULL, position = "identity", ..., parse = FALSE, nudge_x = 0, nudge_y = 0, check_overlap = FALSE, na.rm = FALSE, show.legend = NA, inherit.aes = TRUE ) geom_nodelabel( mapping = NULL, data = NULL, position = "identity", ..., parse = FALSE, nudge_x = 0, nudge_y = 0, label.padding = unit(0.25, "lines"), label.r = unit(0.15, "lines"), label.size = 0.25, na.rm = FALSE, show.legend = NA, inherit.aes = TRUE )
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 jointy specified with
|
... |
Other arguments passed on to |
parse |
If |
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 |
check_overlap |
If |
na.rm |
If |
show.legend |
logical. Should this layer be included in the legends?
|
inherit.aes |
If |
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. |
