convert_fa2sf {SADISA}

Converts different formats to represent multiple sample data

Description

Converts the full abundance matrix into species frequencies If S is the number of species and M is the number of samples, then fa is the full abundance matrix of dimension S by M. The for example fa = [0 1 0;3 2 1;0 1 0] leads to sf = [0 1 0 2;3 2 1 1];

Usage

convert_fa2sf(fa)

Arguments

fa

the full abundance matrix with species in rows and samples in columns

Value

the sample frequency matrix
