Description

This function serves to display a confidence interval in plain text, taking a vector of length 2 or a d \times 2-matrix containing the confidence limits and given number of digits after the comma. A unit can be additionally supplied.

Usage

displayCI(ci, digit = 2, unit = "", text = "none")

Arguments

ci

Vector of length 2 or matrix of size d \times 2, containing the confidence limits.

digit

Examples

a <- 0.05
k <- qnorm(p = 1 - a / 2)
x <- 50
n <- 100
wilson.ci <- (x + k ^ 2 / 2) / (n + k ^ 2) + c(-1, 1) * (k * n ^ 0.5) / 
    (n + k ^ 2) * sqrt(x / n * (1 - x / n) + k ^ 2 / (4 * n))
displayCI(wilson.ci)
displayCI(wilson.ci, digit = 1, unit = "cm", text = "none")
displayCI(wilson.ci, digit = 1, unit = "cm", text = "english")
