mapping |
Set of aesthetic mappings created by |
data |
A data frame. If specified, overrides the default data frame defined at the top level of the plot. |
parse |
If TRUE, the labels will be parsed into expressions and displayed as described in ?plotmath |
... |
other arguments passed on to
|
box.padding |
Amount of padding around bounding box, as unit or number.
Defaults to 0.25. (Default unit is lines, but other units can be specified
by passing |
point.padding |
Amount of padding around labeled point, as unit or
number. Defaults to 0. (Default unit is lines, but other units can be
specified by passing |
arrow |
specification for arrow heads, as created by |
force |
Force of repulsion between overlapping text labels. Defaults to 1. |
max.iter |
Maximum number of iterations to try to resolve overlaps. Defaults to 10000. |
nudge_x , nudge_y |
Horizontal and vertical adjustments to nudge the
starting position of each text label. The units for |
na.rm |
If |
show.legend |
logical. Should this layer be included in the legends?
|
inherit.aes |
If |
label.padding |
Amount of padding around label, as unit or number.
Defaults to 0.25. (Default unit is lines, but other units can be specified
by passing |
label.r |
Radius of rounded corners, as unit or number. Defaults
to 0.15. (Default unit is lines, but other units can be specified by
passing |
label.size |
Size of label border, in mm. |
