Description

I'd like to have a method to transform R2 indices into multiple correlations (R).

I am thinking a an S3 method for sqrt() that transforms appropriate columns might be good.

m <- lm(mpg ~ disp * hp, data = mtcars)
p <- performance::performance(p)
sqrt.performance_model <- function(x) {
    x |> mutate(R2 = sqrt(R2), R2_adjusted = sqrt(R2_adjusted)) |> rename(R = R2, R_adjusted = R2_adjusted)
}
sqrt(p)

What do you think @strengejacke @mattansb @DominiqueMakowski ? This could also be applied in effectsize.

Research direction

Start with the supplied lm() and performance::performance() example and inspect the resulting performance object and its R2 columns. The proposed sqrt.performance_model entry point should produce R and R_adjusted values when sqrt(p) is called; verify the behavior on the example and add coverage for the transformation.
