Calculating Proportionality Between Vectors of Compositional Data.

http://github.com/tpq/propr
http://cran.r-project.org/web/packages/propr

The bioinformatic evaluation of gene co-expression often begins with correlation-based analyses. However, this approach lacks statistical validity when applied to relative count data. This includes, for example, biological data produced by high-throughput RNA-sequencing, chromatin immunoprecipitation (ChIP), ChIP-sequencing, Methyl-Capture sequencing, and other techniques. Two metrics of proportionality, phi [Lovell et al (2015) ] and rho [Erb and Notredame (2016) ], both derived from compositional data analysis, a branch of math dealing specifically with relative data, represent novel alternatives to correlation. This package introduces a programmatic framework for calculating feature dependence through proportionality, as discussed in the cited publications.
