Performs correlations test to the whole dataset.

1 2	correlations_test(dataset, method = "pearson", by.var = TRUE, alternative = "two.sided")

`dataset`	list representing the dataset from a metabolomics experiment.
`method`	correlation method, it can be "pearson", "kendall" or "spearman".
`by.var`	if TRUE then the correlations of the variables will be calculated, if not then the correlations of the samples will be calculated.
`alternative`	alternative argument from cor.test of stats package. Can be "two.sided", "less" or "greater".

Returns a matrix with the correlation values and the p-values

  ## Example of correlations test of variables
  library(specmine.datasets)
  data(cachexia)
  corr.result = correlations_test(cachexia, 
		method = "pearson", by.var = FALSE)
