aes
or
aes_
. If specified and inherit.aes = TRUE
(the
default), it is combined with the default mapping at the top level of the
plot. You must supply mapping
if there is no plot mapping.NULL
, the default, the data is inherited from the plot
data as specified in the call to ggplot
.
A data.frame
, or other object, will override the plot
data. All objects will be fortified to produce a data frame. See
fortify
for which variables will be created.
A function
will be called with a single argument,
the plot data. The return value must be a data.frame.
, and
will be used as the layer data.layer
. These are
often aesthetics, used to set an aesthetic to a fixed value, like
color = "red"
or size = 3
. They may also be parameters
to the paired geom/stat.FALSE
, the default, missing values are removed with
a warning. If TRUE
, missing values are silently removed.NA
, the default, includes if any aesthetics are mapped.
FALSE
never includes, and TRUE
always includes.ggtern() + geom_Tline(Tintercept=.5,arrow=arrow(), colour='red') + geom_Lline(Lintercept=.2, colour='green') + geom_Rline(Rintercept=.1, colour='blue')
