Calculate a correlation and its statistical significance

Returns the correlation and p-value for two variables using a user-specified correlation metric. P-values are estimated analytically, not via permutation-testing.

Usage

get.correlation.p.and.corr(x, y, alternative = 'two.sided', method = 'pearson');

Arguments

x

Vector of numbers to analyze

y

Vector of numbers to analyze

alternative

What is the null-hypothesis?

method

The correlation technique to use (passed directly to cor.test)

Value

Returns a two-element vector containing the correlation and its p-value.

Examples

get.correlation.p.and.corr(
  x = runif(100),
  y = runif(100),
  method = 'pearson'
  );
#> [1] -0.1294731  0.1991894

get.correlation.p.and.corr(
  x = sample(1:10, 100, replace = TRUE),
  y = runif(100),
  method = 'spearman'
  );
#> [1] -0.08565849  0.39678646
