ggvline: Grob function: vline

In hadley/ggplot1: Before there was ggplot2

Description

Aesthetic mappings that this grob function understands:

• none

Usage

ggvline(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

Other options:

• position: vertical position(s) to draw lines

• colour: line colour

• size: line thickness

• linetype: line type

• range: x (or y if slope infinite) range to draw the line. This is sometimes necessary because ggplot isn't smart enough to calculate the entire range of the data

Examples

p <- ggplot(mtcars, aesthetics=list(x = wt, y=mpg))
ggvline(ggpoint(p), position=mean(mtcars$wt), size=2)
