ccrepeSampleTestFunction


 y is a vector.
 if y selected then x must be a vector too



This  simple example of a test measurent function to be used with ccrepe       
 used in the same fashion that cor would be used                                   
 Some properties of the function:                                                  
 1. Be able to take either two inputs which are vectors or one input which         
 is either a matrix or a data frame                                              
 3.In the case of one input, return a matrix in which the (i,j)th entry            
   is the similarity score for column i and column j in the original matrix         
 4.Resulting matrix must be symmetric                                               
 5.The inputs must be named x and y    


The CCREPE (Compositionality Corrected by REnormalizaion and PErmutation) package is designed to assess the significance of general similarity measures in compositional datasets.  In microbial abundance data, for example, the total abundances of all microbes sum to one; CCREPE is designed to take this constraint into account when assigning p-values to similarity measures between the microbes.  The package has two functions:
ccrepe:    Calculates similarity measures, p-values and q-values for relative abundances of bugs in one or two body sites using bootstrap and permutation matrices of the data.
nc.score:  Calculates species-level co-variation and co-exclusion patterns based on an extension of the checkerboard score to ordinal data.
