biotic-package {biotic} | R Documentation |

## 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.
