ci: Confidence interval helper function

In ZachHunter/NicePlots.R: Nice Plots for Data Exploration

Confidence interval helper function

Description

Designed to be used by boot95ci to calculate a bootstrap model of an aggregator function given by agg.

Usage

ci(x, indices, agg)

Arguments

x	numeric vector
indices	numeric vector: Indicies are passed to calculated individual bootstaps of x
agg	character: A string corresponding to the aggregate or central tendency function to be modeled (eg. median, mean, etc.)

Details

This is a convenience function internal to NicePlots and is not exported. The variable agg should be a string corresponding an aggregator function such as mean or median. The indicies designed to passed from the boot function from the package boot and are used to determine calculated the different bootstrap iterations of the agg functions on x.

Value

a number corresponding to a bootstrap iteration of the aggregator function given by agg

data(iris)
#ci(iris$Sepal.Length,"median",seq(1,length(iris$Sepal.Length)))
