Reproducible example for position_jitter() not working

[fkohrt]

It seems to me, the last of the examples of position_jitter() does not work as intended. In other words: The following code...

ggplot2/R/position-jitter.R

Lines 43 to 47 in 8e63882

	#' # Create a jitter object for reproducible jitter:
	#' jitter <- position_jitter(width = 0.1, height = 0.1)
	#' ggplot(mtcars, aes(am, vs)) +
	#' geom_point(position = jitter) +
	#' geom_point(position = jitter, color = "red", aes(am + 0.2, vs + 0.2))

...does not seem to simply shift the jittered points:

But maybe I misunderstood what the example is supposed to show?

Thanks for pointing this out. The position adjustment should be constructed as follows jitter <- position_jitter(width = 0.1, height = 0.1, seed = 0) and then it does what it should. The example should be updated to reflect this.
