This function tests for association between each row vector in
x and y, using one of Pearson's product moment coefficient,
Kendall's tau or Spearman's rho.
See the Details section below for further information.
Arguments
- x
matrixordata.frame.- y
numeric vector of data values. Must have the same length as
ncol(x).- alternative
character string or vector of length
nrow(x). The alternative hypothesis for each row ofx. Values must be one of"two.sided"(default),"greater"or"less".- method
character string indicating how to measure the association. Available options are:
"pearson"Pearson's product moment coefficient
"kendall"Kendall's tau
"spearman"Spearman's rho
- conf.level
numerical value or numeric vector of length
nrow(x). The confidence levels of the intervals. All values must be in the range of \([0:1]\) orNA.- ...
further arguments to
cor.test
Value
A list containing two elements:
- statistic
A numeric vector, the values of the test statistic
- significance
A numeric vector, the p-values of the selected test
