reflimR: Reference Limit Estimation Using Routine Laboratory Data

The reflimR package provides a simple and robust three-step procedure for the estimation of reference intervals from routine laboratory data that may contain an unknown proportion of pathological results. Reference intervals play a crucial role in the medical interpretation and statistical evaluation of laboratory results.

To install the reflimR package, open R and enter the following command in the console:

install.packages("reflimR")

This command will download the package from CRAN. Once the installation is complete, load the package into your R session using the following command:

library(reflimR)

The package will then be ready for use in your R environment (e.g. in RStudio). To see the documentation of the package with all its help files, please enter

help(package = reflimR)

Here is a basic example demonstrating how to use reflimR:

library(reflimR)

x <- c(rnorm(800, 100, 10), rnorm(100, 70, 15), rnorm(100, 125, 15))
reflim(x, targets = qnorm(c(0.025, 0.975), 100, 10))
