About the CCREPE category

User manual || Tutorial

Description: CCREPE is an R package designed to detect significant correlations in compositional data. Compositional data often contains ‘spurious’ correlation which can lead naive analyses astray. Microbial data is compositional in nature and thus inferring potential ecological networks is often difficult. The CCREPE package comes with two functions:

  • ccrepe, which provides compositionality-corrected p-values, q-values, and Z-scores for all pairwise correlations within one dataset or between two datasets;
  • nc.score, which is an extension of the checkerboard score to ordinal data and thus provides a similarity measure more appropriate for compositional data analysis.
