This is ggplot2's segment with rounded ends. It's mainly
included in ggmap for historical reasons.
Single line segments with rounded ends
Usage
geom_leg(mapping = NULL, data = NULL, stat = "identity",
position = "identity", arrow = NULL, lineend = "round", na.rm = FALSE,
show.legend = NA, inherit.aes = TRUE, ...)
geom_leg(mapping = NULL, data = NULL, stat = "identity",
position = "identity", arrow = NULL, lineend = "round", na.rm = FALSE,
show.legend = NA, inherit.aes = TRUE, ...)
Arguments
mapping
mapping
data
data
stat
stat
position
position
arrow
arrow
lineend
Line end style (round, butt, square)
na.rm
If FALSE (the default), removes missing values with
a warning. If TRUE silently removes missing values.
show.legend
logical. Should this layer be included in the legends?
NA, the default, includes if any aesthetics are mapped.
FALSE never includes, and TRUE always includes.
inherit.aes
If FALSE, overrides the default aesthetics,
rather than combining with them. This is most useful for helper functions
that define both data and aesthetics and shouldn't inherit behaviour from
the default plot specification, e.g. borders.
