Function to calculate abundance, diversity, and evolutionary plasticity of an orthologous group (OG).
this argument is an object of class 'OGP' (
a single logical value specifying to display detailed messages (when verbose=TRUE) or not (when verbose=FALSE).
This method computes the abundance and diversity of an OG, and derives the evolutionary plasticity as described in Castro et al. (2008) and Dalmolin et al. (2011). The OG diversity corresponds to the normalized Shannon's diversity index and estimates the distribution of orthologous proteins across the species listed in the input dataset. The OG abundance is simply the ratio between the number of orthologs of a given OG and the number of organisms listed in the group. Evolutionary Plasticity Index is calculated as described in Dalmolin et al (2011).
A processed object of class 'OGP', including COG's abundance, diversity, and plasticity results.
