ggrepel functions | R Documentation |
These functions are minor modifications of those in the ggrepel
package. geom_dag_text_repel adds text directly to the plot.
geom_dag_label_repel draws a rectangle underneath the text, making it easier
to read. The text labels repel away from each other and away from the data
points.

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 |
segment.color , segment.size |
See |
fontface |
A character vector. Default is "bold" |
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?
|
