Zooplankton: Zooplankton Depredation

In abd: The Analysis of Biological Data

Description

Diversity of zooplankton (zooplankton) prey in each of 5 replicate blocks (block) of three treatment levels (treatment). By default, block is not coded as a factor.

Usage

data(Zooplankton)

Format

A data frame with 15 observations on the following 3 variables.

treatment

a factor with levels control, high, and low

zooplankton

a numeric vector

block

a numeric vector

Source

inferred from Svanbäck, R. and D.I. Bolnick. 2007. Intraspecific competition drives increased resource use diversity within a natural population. Proceedings of the Royal Society of London Series B, Biological Sciences 274: 839-844.

Examples

data(Zooplankton)
Zooplankton

Zooplankton$block <- factor(Zooplankton$block)
str(Zooplankton)

aov.fit <- aov(zooplankton ~ block + treatment,
  data = Zooplankton)
summary(aov.fit)

Loading required package: Matrix

The 'mosaic' package masks several functions from core packages in order to add 
additional features.  The original behavior of these functions should not be affected by this.

Note: If you use the Matrix package, be sure to load it BEFORE loading mosaic.
