position_jitter(width=NULL, height=NULL, ...)

Jitter points to avoid overplotting

This page describes position_jitter, see layer and qplot for how to create a complete plot from individual components.

Parameters

Parameters control the appearance of the position. In addition to the parameters listed below (if any), any aesthetic can be used as a parameter, in which case it will override any aesthetic mapping.

width: degree of jitter in x direction. Defaults to 40\% of the resolution of the data.
height: degree of jitter in y direction. Defaults to 40\% of the resolution of the data.

Returns

This function returns a position object.

Examples

> qplot(am, vs, data=mtcars) 
  
>  
> # Default amount of jittering will generally be too much for 
> # small datasets: 
> qplot(am, vs, data=mtcars, position="jitter") 
  
> # Control the amount as follows 
> qplot(am, vs, data=mtcars, position=position_jitter(w=0.1, h=0.1)) 
  
>  
> # The default works better for large datasets, where it will 
> # will up as much space as a boxplot or a bar 
> qplot(cut, price, data=diamonds, geom=c("boxplot", "jitter"))
