## Example 1: mcr(iris[,-5],1,c(2,3,4)) ## Returns multiple correlation between Sepal.Length ## and the other variables ## Example 2 mu<-c(10,12,13,14) sig<-matrix(0,4,4) diag(sig)<-c(2,1,1,3) da<-MASS::mvrnorm(25,mu,sig) mcr(da, 2,c(1,3,4)) ## Returns Multiple correlation when the data matrix ## simulated from a quadrivariate normal distribution ## is given as input ## Example 3 da<-var(iris[,-5]) mcr(da,3,c(1,2,4),FALSE) ## Returns multiple correlation between Petal.Width ## and the other variables when the correlation matrix ## is given as input
