This function computed the linear correlation between two vectors or a correlation matrix for an input matrix.
The following methods to compute linear correlations are implemented in this function:
lin.cor(x, y = NULL, method = "pearson", test.na = FALSE)a numeric vector, matrix, or data.frame.
a numeric vector that should be correlated with x.
the method to compute the linear correlation between x and y.
a boolean value indicating whether input data should be checked for NA values.
method = "pearson" : Pearson's correlation coefficient (centred).
method = "pearson2" : Pearson's uncentred correlation coefficient.
method = "sq_pearson" . Squared Pearson's correlation coefficient.
method = "kendall" : Kendall's correlation coefficient.
method = "spearman" : Spearman's correlation coefficient.
