The goal of concordancer is to provide an Rcpp implementation of Lin's Concordance Correlation Coefficient (CCC).
Install the latest release from CRAN:
install.packages("concordancer")
You can install the development version of concordancer from GitHub with:
# install.packages("devtools")
devtools::install_github("troyjcross/concordancer")
This is a basic example which shows you how to solve a common problem:
library(concordancer)
# Create x and y
x <- rnorm(100, sd = 1)
y <- rnorm(length(x), sd = 0.5)
# Calculate CCC
result <- ccc(x,y)
print(result)
