In JenC36/JACtools: A Set of Relatively Useful Functions

Place Sample Size on Boxplots at Mean y-value

Description

This function returns the length (number of observations, n) and the mean of a vector.

Usage

give_n(x)

Arguments

x	A numeric vector.

Details

When used with ggplot, it can to place the number of observations within the box of a box-and-whisker plot
into the box at the mean value of the observations.

Examples

color.dat <- c(rep('A', 10),rep('B', 10))
y.dat <- c(rnorm(10,2, 2), rnorm(10,5,5))
example.dat <- data.frame(color.dat,y.dat)
(ggplot2::ggplot(example.dat, aes(y=y.dat, x=color.dat, fill=color.dat))
		+ geom_boxplot(color='grey30', aes(fill=color.dat))
		+ stat_summary(fun.data = give_n, geom = "text", position = position_dodge(width = 0.75), size = 5, color='red')
		+ scale_fill_manual('', values=c("grey80","grey60"))
		+ theme_bw())
