DaphniaResistance: Daphnia Resistance to Cyanobacteria

In abd: The Analysis of Biological Data

Description

Resistance of Daphnia eggs to different levels of cyanobacteria (cyandensity) from 1962-1997.

Usage

data(DaphniaResistance)

Format

A data frame with 32 observations on the following 2 variables.

density

a factor with levels: high, low, and med

resistance

a numeric vector

Examples

data(DaphniaResistance)
str(DaphniaResistance)


bwplot(resistance ~ density, DaphniaResistance)
# with such a small data set, we can display all the data rather than a summary
xyplot(resistance ~ density, DaphniaResistance)
histogram( ~ resistance| density, DaphniaResistance, 
	strip=FALSE, strip.left = TRUE,
	layout=c(1,3)

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.
