biotic-package: biotic: A package for calculating a range of UK freshwater invertebrate
biotic indices.
Description
The biotic package provides a main calculation function, wrapper
functions for easy calculation of specific indices and a data
transposition function which can be used to prepare data for analysis
when needed.
Main function
The main function is calcindex which allows the
calculation of any of the indices implemented.Wrapper functions
A function is provided for each of the individual indices to
allow for quick calculations. An example is
calcPSI which implements calculation of the
PSI index of sedimentation impacts.Data transposition function
The transposedata function allows for simple
conversion between the default format with taxa in rows and
samples in columns and the transpose of this.
