Alternative formula interface for cor.test

stats::cor.test() in stats accepts formulas of the shape ~ y + x. The mosaic package allows the use of y ~ x as an alternative formula shape.

# S3 method for formula
cor_test(formula, ...)

cor.test(x, ...)

cor_test(x, ...)

# S3 method for default
cor_test(x, y, ...)

Arguments

formula

a formula

...
