Function to calculate R2 (R-squared) in R - Stack Overflow

    https://stackoverflow.com/questions/40901445/function-to-calculate-r2-r-squared-in-r
    R squared between two vectors is just the square of their correlation. So you can define you function as: rsq <- function (x, y) cor (x, y) ^ 2. Sandipan's answer will return you exactly the same result (see the following proof), but as it stands it appears more readable (due to the evident $r.squared ). See more
