niche.overlap.boot.pair: Boostrap the niche overlap indices

In helixcn/spaa: SPecies Association Analysis

Description

bootstrap the niche overlap indices between a pair of species. This is an internal function used by niche.overlap.boot, use niche.overlap.boot instead.

Usage

niche.overlap.boot.pair(vectorA, vectorB, method = c("levins",
     "schoener", "petraitis", "pianka", "czech", "morisita"),
      times = 1000, quant = c(0.025, 0.975))

Arguments

vectorA	A numeric vector containing species A's abundance or importance value.
vectorB	A numeric vector containing species B's abundance or importance value.
method	Name of the index to use.
times	Number of bootstraps
quant	Confidence intervals of the bootstrap results.

Value

This function will return a vector containing:\ "Observed", \ "Boot mean", \ "Boot std", \ "Boot CI1", \ "Boot CI2", \ "times" \

Note

This is an internal function, please use niche.overlap.boot.
