correls2 function

Correlation between a vector and a matrix

Fast Pearson/Spearman correlation where y is vector, x is matrix, adapted from stats::cor.test .

correls2(y, x, method = "pearson", use = "complete.obs")

Arguments

• y: Numerical vector
• x: Matrix
• method: Type of correlation, either "pearson" or "spearman".
• use: Optional character string giving a method for computing covariances in the presence of missing values. See cor

Returns

Matrix with columns containing the correlation statistic, either Pearson r or Spearman rho, and p-values for each column of x correlated against vector y

Details

For speed, p-values for Spearman's test are computed by asymptotic t approximation, equivalent to cor.test with exact = FALSE.
