geom_jitter

0th

Percentile

Points, jittered to reduce overplotting.

The jitter geom is a convenient default for geom_point with position = 'jitter'. See position_jitter to see how to adjust amount of jittering.

Usage
geom_jitter(mapping = NULL, data = NULL,
    stat = "identity", position = "jitter", na.rm = FALSE,
    ...)
Arguments
mapping
The aesthetic mapping, usually constructed with aes or aes_string. Only needs to be set at the layer level if you are overriding the plot defaults.
data
A layer specific dataset - only needed if you want to override the plot defaults.
stat
The statistical transformation to use on the data for this layer.
position
The position adjustment to use for overlappling points on this layer
na.rm
If FALSE (the default), removes missing values with a warning. If TRUE silently removes missing values.
...
other arguments passed on to layer. This can include aesthetics whose values you want to set, not map. See layer for more details.
Aesthetics

[results=rd,stage=build]{ggplot2:::rd_aesthetics("geom", "jitter")} p <- ggplot(mpg, aes(displ, hwy)) p + geom_point() p + geom_point(position = "jitter")

# Add aesthetic mappings p + geom_jitter(aes(colour = cyl))

# Vary parameters p + geom_jitter(position = position_jitter(width = .5)) p + geom_jitter(position = position_jitter(height = .5))

# Use qplot instead qplot(displ, hwy, data = mpg, geom = "jitter") qplot(class, hwy, data = mpg, geom = "jitter") qplot(class, hwy, data = mpg, geom = c("boxplot", "jitter")) qplot(class, hwy, data = mpg, geom = c("jitter", "boxplot"))

geom_point for regular, unjittered points, geom_boxplot for another way of looking at the conditional distribution of a variable, position_jitter for examples of using jittering with other geoms
