This procedure takes a list that is the result of the downsizeGC.all method and transforms
it in a matrix of meaned downsied values. Each element of this list contains downsizing results for a given
sample. This result is a matrix in lines the number of simulations and in columns the different downsizing levels
Usage
downsizedRichnessL2T(richness.list)
Arguments
richness.list
: the result of the downsizeGC.all method
Value
A matrix with the samples in rows and the downsizing in columns
