Description

Data on lab experiments on the density- and size-dependent predation rate of an African reed frog, Hyperolius spinigularis, from Vonesh and Bolker 2005

Usage

data(reedfrogs)

Format

Various data with variables:

density

initial tadpole density (number of tadpoles in a 1.2 x 0.8 x 0.4 m tank) [experiment 1]

pred

factor: predators present or absent [experiment 1]

size

factor: big or small tadpoles [experiment 1]

surv

number surviving

propsurv

proportion surviving (=surv/density) [experiment 1]

Examples

# NOT RUN {
