XY {peramo}

Permutation Test for Correlation Between Paired Samples

Description

XY performs permutation test on correlation coefficients.

Usage

XY(a, b, rand = 9999, seed = 1, method = c("pearson", "kendall", "spearman"))

Arguments

a

a numeric vector, the first variable.

b

a numeric vector, the second variable.

rand

an integer, the number of randomization samples. The default value is 9999.

seed

an integer, the seed for random number generation. Setting a seed ensures the reproducibility of the result. See set.seed for more details.

method

correlation coefficient, "pearson", "kendall", or "spearman".

Value

XY returns an one-row data frame with 2 columns:

cor

the correlation coefficient.

pval

the p-value.
