Package: cccrm Title: Concordance Correlation Coefficient for Repeated (and Non-Repeated) Measures Version: 3.0.6 Date: 2026-01-27 Authors@R: c(person(given = c("Josep", "Lluis"), family = "Carrasco", role = c("aut", "cre"), email = "jlcarrasco@ub.edu"), person(given = c("Gonzalo", "Peon"), family = "Pena", role = "aut")) Depends: R (>= 4.1) Imports: nlme, dplyr, Deriv, tidyselect, progressr, furrr, nlmeU, parallelly, purrr, tidyr, lifecycle, future, MASS, ggplot2 Description: Estimates the Concordance Correlation Coefficient to assess agreement. The scenarios considered are non-repeated measures, non-longitudinal repeated measures (replicates) and longitudinal repeated measures. It also includes the estimation of the one-way intraclass correlation coefficient also known as reliability index. The estimation approaches implemented are variance components and U-statistics approaches. Description of methods can be found in Fleiss (1986) and Carrasco et al. (2013) .
