get_pvals: P-values for correlations in a data frame or matrix

Description

This is a stripped down version of the "cor.mtest()" function from the "corrplot" package. It uses the stats::cor.test() function to calculate pairwise p-values. Unlike the corrplot version, this only calculates p-values, and not confidence intervals. Credit to corrplot for this code, I only replicate it here to avoid depending on their package for a single function.

Usage

get_pvals(X, ...)

Value

Matrix of p-values

Arguments

X

A numeric matrix or data frame

...

Additional arguments passed to function cor.test(), e.g. conf.level = 0.95.

Examples

# a matrix of random numbers, 3 cols
x <- matrix(runif(30), 10, 3)

# get correlations between cols
cor(x)

# get p values of correlations between cols
get_pvals(x)
