Q-Q plot coordinates against a reference distribution

Usage

mrm_qq_plot(sample, dist = "norm", ...)

Arguments

sample: Numeric vector.
dist: Either "norm", "exp", "unif", "t", "chisq" (any base q<dist> works).
...: Additional parameters passed to q<dist>.

Value

data.frame with rank, empirical, theoretical, plotting_position columns (Blom 1958 plotting positions).

Examples

set.seed(2026)
x <- rnorm(100)
qq <- mrm_qq_plot(x, dist = "norm")
head(qq)
