piosphere {ade4} | R Documentation

## Plant traits response to grazing

### Description

Plant species cover, traits and environmental parameters recorded around livestock watering points in different habitats of central Namibian farmlands. See the Wesuls et al. (2012) paper for a full description of the data set.

### Usage

    data(piosphere)

### Format

`piosphere` is a list of 4 components.

veg

  is a data frame containing plant species cover

traits

  is a data frame with plant traits

env

  is a data frame with environmental variables

habitat

  is a factor describing habitat/years for each site

### Examples

    data(piosphere)
    names(piosphere)
    afcL <- dudi.coa(log(piosphere$veg + 1), scannf = FALSE)
    acpR <- dudi.pca(piosphere$env, scannf = FALSE, row.w = afcL$lw)
    acpQ <- dudi.hillsmith(piosphere$traits, scannf = FALSE, row.w = afcL$cw)
    rlq1 <- rlq(acpR, afcL, acpQ, scannf = FALSE)
    plot(rlq1)
