calcPred: Predation Rate Calculation

In eahamman/Predator.Diversity: Simulations and fitting of functional responses

Predation Rate Calculation

Description

Predation Rate Calculation

Usage

calcPred(parmat, svec, preyvec, predvec, afun = inda, hfun = indh)

Arguments

parmat	matrix of parameters that define predator attack rates and handling times
svec	vector of size classes (upper bounds)
preyvec	vector of prey densities
predvec	vector of predator densities
afun	attack-rate function
hfun	handling time function

Examples

svec <- 1:10
preyvec <- rep(1,10)
predvec <- 1
parmat <- matrix(c(1,1,1,   ## c,d,g pred 1
                   1,1,1),  ## c,d,g pred2
       byrow=TRUE,
       nrow=2,dimnames=list(c("pred1","pred2"),c("c","d","g")))
## calcPred()
