- mapping
Set of aesthetic mappings created by 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.
- data
The data to be displayed in this layer. There are three
options:
If 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. A function can be created
from a formula (e.g. ~ head(.x, 10)).
- method
a character string indicating which correlation coefficient (or
covariance) is to be computed. One of "pearson" (default), "kendall", or
"spearman".
- alternative
a character string specifying the alternative hypothesis,
must be one of "two.sided" (default), "greater" or "less". You can specify
just the initial letter.
- cor.coef.name
character. Can be one of "R" (pearson coef),
"rho" (spearman coef) and "tau" (kendall coef). Uppercase and
lowercase are allowed.
- label.sep
a character string to separate the terms. Default is ", ", to
separate the correlation coefficient and the p.value.
- label.x.npc, label.y.npc
can be numeric or character
vector of the same length as the number of groups and/or panels. If too
short they will be recycled.
If numeric, value should
be between 0 and 1. Coordinates to be used for positioning the label,
expressed in "normalized parent coordinates".
If character,
allowed values include: i) one of c('right', 'left', 'center', 'centre',
'middle') for x-axis; ii) and one of c( 'bottom', 'top', 'center', 'centre',
'middle') for y-axis.
If too short they will be recycled.
- label.x, label.y
numeric Coordinates (in data units) to be used
for absolute positioning of the label. If too short they will be recycled.
- output.type
character One of "expression", "latex", "tex" or "text".
- digits, r.digits, p.digits
integer indicating the number of decimal
places (round) or significant digits (signif) to be used for the correlation
coefficient and the p-value, respectively..
- r.accuracy
a real value specifying the number of decimal places of
precision for the correlation coefficient. Default is NULL. Use (e.g.) 0.01
to show 2 decimal places of precision. If specified, then r.digits is
ignored.
- p.accuracy
a real value specifying the number of decimal places of
precision for the p-value. Default is NULL. Use (e.g.) 0.0001 to show 4
decimal places of precision. If specified, then p.digits is ignored.
- geom
The geometric object to use display the data
- position
Position adjustment, either as a string, or the result of
a call to a position adjustment function.
- 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.
It can also be a named logical vector to finely select the aesthetics to
display.
- 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().
- ...
other arguments to pass to geom_text or
geom_label.
