[R] Bimodal distribution

[Greg Snow]

You could use:

library(TeachingDemos)

x <- c(rnorm(1000,0,1),rnorm(1000,3,1))
TeachingDemos:::vis.test( x, TeachingDemos:::vt.normhist )

Then click on the plot that looks most different.

Sorry about needing TeachingDemos::: for now, the functions were accidentally left out of the NAMESPACE file, this has been fixed and will not be needed for version 2.6 on.
