stat_unique: Remove duplicates.
Description
Remove duplicates.Usage
stat_unique(mapping = NULL, data = NULL, geom = "point",
position = "identity", na.rm = FALSE, show.legend = NA,
inherit.aes = TRUE, ...)
Arguments
mapping
The aesthetic mapping, usually constructed with
aes or aes_string. Only needs to be set
at the layer level if you are overriding the plot defaults. data
A layer specific dataset - only needed if you want to override
the plot defaults.
geom
The geometric object to use display the data
position
The position adjustment to use for overlapping points
on this layer
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.
...
other arguments passed on to layer. This can
include aesthetics whose values you want to set, not map. See
layer for more details. Aesthetics
