Arguments
x 
Object. 
y 
Object. 
i 
indices specifying elements to extract or replace. Indices are
numeric or character vectors or empty (missing) or
NULL . Numeric values are coerced to integer as by
as.integer (and hence truncated towards zero).
Character vectors will be matched to the names of the
object (or for matrices/arrays, the dimnames ):
see ‘Character indices’ below for further details.
For [ indexing only: i , j , ... can be
logical vectors, indicating elements/slices to select. Such vectors
are recycled if necessary to match the corresponding extent.
i , j , ... can also be negative integers,
indicating elements/slices to leave out of the selection.
When indexing arrays by [ a single argument i can be a
matrix with as many columns as there are dimensions of x ; the
result is then a vector with elements corresponding to the sets of
indices in each row of i .
An index value of NULL is treated as if it were integer(0) . 
j 
indices specifying elements to extract or replace. Indices are
numeric or character vectors or empty (missing) or
NULL . Numeric values are coerced to integer as by
as.integer (and hence truncated towards zero).

color 
ScaleDiscrete .
Desired ggplot2 color scale. Must supply discrete values. When set NULL ,
the default ggplot2 color palette will be used. If manual color definitions
are desired, we recommend using ggplot2::scale_color_manual() .
To set the discrete color palette globally, use: options(acid.color.discrete = ggplot2::scale_color_viridis_d())

labels 
list .
ggplot2 labels.
See ggplot2::labs() for details.

.xname 
Name of object defined in x .
Not intended to be used directly. 
.yname 
Name of object defined in y .
Not intended to be used directly. 
... 
Additional arguments.
