display.untb {untb}R Documentation

Animation of neutral ecological drift

Description

Displays an ongoing simulation of neutral ecological drift using nice colours and a simple animation technique

Usage

display.untb(start, gens=100, prob.of.mutate = 0.001, cex=3, individually
= TRUE, flash = FALSE, t1 = 0, flashsleep = 0.1, ...)

Arguments

start Starting ecosystem; coerced to class census. Usually, pass an object of class count; see examples. To start with a monoculture of size 10, use start=rep(1,10) and to use start=1:10.
prob.of.mutate Probability of mutation.
individually Boolean, indicating whether the ecosystem should evolve simultaneously (FALSE), or individually (TRUE)
gens Number of generations to simulate
cex The size of the dots used for plotting, defaulting to 3
flash Boolean, with TRUE meaning to indicate the site of a death/birth with a flashing ring; and default FALSE meaning to omit the flashing ring and thus simulate much faster
t1 Time delay between generations
flashsleep In function display.untb(), time delay of flashing ring
... Further arguments passed to plot() and points().
