displayCI: Generate strings of a confidence interval from a matrix

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 = "")

Arguments

ci

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

digit

Number of digits after the comma.

unit

Character string denoting a unit of measurement.

Value

• A character string to be inserted in plain text.

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")
