In lsaravia/EcoIndicators: An Algorithm for the Identification of Indicator Taxonomic Units and their Use in Analyses of Ecosystem State

Returns the frequency of any taxonomic unit in a selected combination of environmental factors

Description

Returns the frequency of any taxonomic unit in a selected combination of environmental factors

Usage

sp_hypercube(env, sp, partitions = 3, intersection = TRUE)

Arguments

env	Vector or matrix of quantitative environmental data
sp	A vector or matrix of the abundance or presence of a species or taxonomic unit registered in the same samples as environmental data.
partitions	Number of intervals in which to divide the range of each variable.
intersection	logical, in case of param sp has two or more species

Value

An object of class 'ftable' with the abundance of a species or combination of them in a grid of environmental variables.

Examples

data(soilandfauna)

# Selecting community (species) data

com <- soilandfauna[,18:60]

# Selecting environmental data

env <- soilandfauna[,3:17]

# Obtaining the presence of the Onychiuridae species in a grid 
# of environmental variables 

sp_hypercube(env[,c("P","OM","N")],com[,"Onychiuridae"],5)

# Obtaining the simultaneous presence of four species in a grid 
# of environmental variables

sp_hypercube(env[,c("P","OM","N")],com[,c("Onychiuridae","Isotomidae", 
"Eupodoidea", "Aporrectodea_rosea",5)
