DImodels (version 1.3.3)

sim0_design: The "sim0_design" Dataset

Description

This dataset contains a set of proportions p1 to p3 where each row sums to 1. It is used as the design matrix for simulating other datasets in the DImodels package.

Usage

data("sim0_design")

Format

A data frame with 16 observations on the following 5 variables:

community

A numeric vector identifying each unique community, i.e., two rows with the same community value also share the same set of p1 to p3 values.

richness

A numeric vector indicating the number of species in the initial composition, i.e., the number of proportions from p1 to p3 that are >0.

p1

A numeric vector indicating a proportion (of species 1).

p2

A numeric vector indicating a proportion (of species 2).

p3

A numeric vector indicating a proportion (of species 3).

Details

The columns p1 to p3 form a simplex space.

Examples

## Load the sim0_design data
  data(sim0_design)
## View the first five entries
  head(sim0_design)
## Explore the variables in design_a
  str(sim0_design)

## Check that the proportions sum to 1 (required for DI models)
## p1 to p3 are in the 3rd to 5th columns in sim0_design
  sim0_design_sums <- rowSums(sim0_design[3:5])
  summary(sim0_design)
