ggquantile: Grob function: quantiles

In hadley/ggplot1: Before there was ggplot2

Grob function: quantiles

Description

This can be used a continuous analogue of a boxplot (see ggboxplot) Lines will be automatically sized to reflect their distance from the median.

Usage

ggquantile(plot, aesthetics = list(), ..., data = NULL)

Arguments

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

Details

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
