sp.band: interpolate species richness for each elevational band

In Sz-Tim/sevcheck: It's pronounced 'sev-check'

interpolate species richness for each elevational band

Description

This function interpolates species, genus, and subfamily richness for a sequence of elevational bands based on the range limits of a set of species.

Usage

sp.band(sp.df, els)

Arguments

sp.df	Dataframe with columns 'Binomial', 'LowEl', 'HighEl'
els	Vector of elevations

Value

Returns a list with items "sp", "g", and "sf" which each contain a vector of interpolated richness values

Examples

sp.df <- data.frame(Binomial=LETTERS[1:10],
                    Genus=rep(letters[1:3], times=c(2,7,1)),
                    Subfamily=rep(c("SF1", "SF2", times=c(2,8))),
                    LowEl=runif(10, 0, 1000))
sp.df$HighEl <- sp.df$LowEl + runif(10, 0, 1000)
els <- seq(0, 2000, by=100)
sp.band(sp.df, els)
