responseplot.diver {DiversityOccupancy} R Documentation

## plot the response of the calculated alpha diversity to the change of a particular variable

### Description

This function takes a modeldiversity object and one of the variables used to predict the alpha diversity index, and makes a plot showing the response of the diversity index against the selected variable. This function automatically limits the values of that variable to the maximum and minimum values of the dataset.

### Usage

responseplot.diver(model, variable)


### Arguments

 model A result from the model.diversity function. variable The variable of which the response is to be ploted.

### Value

a ggplot object plotting the alpha diversity response to the selected variable.

### Examples

## Not run:
data("IslandBirds")
data("Daily_Cov")
data("siteCov")

#Model the abundance for 5 bird species and calculate alpha diversity from that

BirdDiversity <-diversityoccu(pres = IslandBirds, sitecov = siteCov,
obscov = Daily_Cov,spp = 5, form = ~ Day + Wind + Time + Rain +
Noise ~ Elev + AgroFo + SecVec + Wetland + Upland)

#Select the best model that explains diversity using genetic algorithms
set.seed(123)
glm.Birdiversity <- model.diversity(BirdDiversity, method = "g")

#see the best models

glm.Birdiversity\$Best.model

#plot the response of diversity to individual variables

plot(glm.Birdiversity, elev)

## End(Not run)
