sqi: SQI

In SCCWRP/SQI: Calculate Stream Quality Index Scores From Stream Data

SQI

Description

Stream quality index function

Usage

sqi(datin, wq_mod_in = NULL, hab_mod_in = NULL, lothrsh = 0.1,
  hithrsh = 0.9)

Arguments

datin	input data.frame with chemical, physical, and biological data
wq_mod_in	input model object for predicting stressed state for water quality
hab_mod_in	input model object for prediction stressed state for habitat
lothrsh	numeric indicating lower threshold for low stress
hithrsh	numeric indicating upper threshold for high stress

Details

See sampdat for required input format. wq_mod_in and hab_mod_in are both glm objects (wqglm and habglm) included with the package.

Value

a data.frame same as datin but with new columns for pChem, pHab, pChemHab, BiologicalCondtion, WaterChemistryCondition, HabitatCondition, OverallStressCondition, and StreamHealthIndex
