Partial correlation via ppcor — morie_ppcor

Thin extender over ppcor::pcor (matrix-wise) or ppcor::pcor.test (when y and z are supplied) for partial correlations controlling for one or more variables.

Usage

morie_ppcor_partial(x, y = NULL, z = NULL, method = "pearson", ...)

Arguments

x: Numeric vector, matrix, or data frame. When y and z are NULL, the full pairwise partial correlation matrix is returned via ppcor::pcor.
y: Optional second numeric vector.
z: Optional numeric vector / matrix of control variables.
method: Correlation method ("pearson", "spearman", or "kendall"), forwarded to ppcor.
...: Further arguments forwarded to the upstream function.

Value

A list with $method (qualified upstream name) and $raw (the upstream return object).

Examples

if (requireNamespace("ppcor", quietly = TRUE)) {
  set.seed(1)
  x <- rnorm(40); z <- rnorm(40); y <- x + z + rnorm(40)
  morie_ppcor_partial(x, y, z)
