plot.hotelling.test {Hotelling}

Plots the results from a permutation based version of Hotelling's T-squared test for the difference in two multivariate sample means

Description

Plots a histogram of the distribution of the permuted test statistics for a permutation version of Hotelling's T-squared

Usage

## S3 method for class 'hotelling.test'
plot(x, ...)

Arguments

x

an object of type hotelling.test

...

any additional arguments to be passed to the hist command

Details

This function only works if you have performed a permutation test. It will return an error message if not. It could be programmed to draw the relevant F distribution in the standard case, but this seems rather pointless.

Examples

data(bottle.df)
bottle.df = subset(bottle.df, Number == 1)
bottle.df$Number = rep(1:2,c(10,10))
fit = hotelling.test(.~Number, bottle.df, perm = TRUE)
plot(fit)
plot(fit, col = "lightblue")
