simSpp: Community simulator for running cgSim.

In ECGen/ComGenR: Functions for COMmunity GENetics analyses in R

Description

Generates a matrix of species allelic values.

Usage

simSpp(n = "number of species", het.values = c(5, 21), allelic.range = c(0, 3))

Arguments

n	Number of species.
het.values	Range of heterozygote values.
allelic.range	Range of allelic values.

Details

This function provides a simple way to populate a set of phenotypic values for a model community to be used in a simulation of community genetics effects.

Examples

##---- Should be DIRECTLY executable !! ----
##-- ==>  Define data, use random,
##--	or do  help(data=index)  for the standard data sets.

## The function is currently defined as
function (n = "number of species", het.values = c(5, 21), allelic.range = c(0, 
    3)) 
{
    if (n == "number of species") {
        n <- 25
    }
    com <- matrix(NA, nrow = n, ncol = 2)
    com[, 1] <- runif(n, het.values[1], het.values[2])
    com[, 2] <- runif(n, allelic.range[1], allelic.range[2])
    com. <- com
    com.[, 1] <- (com[, 1] - 0.5 * com[, 2])/2
    com.[, 2] <- (com[, 1] + 0.5 * com[, 2])/2
    return(com.)
  }
