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
