ggquantile {ggplot} | R Documentation |
Add quantile lines from a quantile regression
ggquantile(plot = .PLOT, aesthetics=list(), ..., data=NULL)
plot |
the plot object to modify |
aesthetics |
named list of aesthetic mappings, see details for more information |
... |
other options, see details for more information |
data |
data source, if not specified the plot default will be used |
This can be used a continuous analogue of a boxplot (see grob_boxplot
)
Lines will be automatically sized to reflect their distance from the median.
Aesthetic mappings that this grob function understands:
x
:x position (required)
y
:y position (required)
weight
: observation weights
These can be specified in the plot defaults (see ggplot
) or
in the aesthetics
argument. If you want to modify the position
of the points or any axis options, you will need to add a position scale to
the plot. These functions start with ps
, eg.
pscontinuous
or pscategorical
Other options:
quantiles
:quantiles to display
formula
:formula to use in quantile regression
