auc: A function to compute area under a curve.

In leppott/XC95: Extirpation Analysis for Benthic Macroinvertebrates and Fish

Description

Used in other functions in this library (taxon.response(), taxon.response.sort(), and tolerance()). Different versions for response and tolerance.

Usage

auc(xrange, mod, dense.N, taus, auc.version = "response")

Arguments

xrange	y
mod	x
dense.N	the number of areas to cut into in the calculation of area under the curve; default = 201
taus	determine the output the percentile of env variable; default = c(0,95,100) for response.
auc.version	calculation version, "response" or "tolerance"; default = "response".

Value

returns area under the specified curve.

Examples

xrange <- 1
lrm1 <- 2

# response version

dense.N <- 201
taus=c(0,95,100)
#' lrm1.95f <- auc.response(xrange, lrm1, dense.N, taus, "response")
# tolerance version

taus = c(50,95)
lrm195f <- auc(xrange, lrm1, dense.N, taus, "tolerance")
