动画中性生态漂流
译者：生物统计家园网 机器人LoveR
描述----------Description----------
Displays an ongoing simulation of neutral ecological drift using nice colours and a simple animation technique
用漂亮的颜色和简单的动画技术，显示正在进行的模拟中性的生态漂流
用法----------Usage----------
display.untb(start, gens=100, prob.of.mutate = 0, cex=3, individually
= TRUE, ask = FALSE, flash = FALSE, delay = 0, cols=NULL, ...)
参数----------Arguments----------
参数：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 start with a system of maximal diversity (ie all singletons), use start=1:10
启动生态系统;强制转换为类人口普查。通常情况下，通过对象的类别数;看到的例子。要启动与单养大小为10，使用start=rep(1,10)，并开始系统的最大多样性（即所有的singleton），使用start=1:10
参数：gens
Number of generations to simulate
数代模拟
参数：prob.of.mutate
Probability of mutation. The default of zero corresponds to theta=0 and this means that any ecosystem will eventually become a monoculture (it is particularly instructive to watch this happen, especially with a starting ecosystem of maximal diversity: but be warned, this can take a long time, especially for ecosystems with a large number of individuals). Nonzero values mean that a nontrivial dominance-diversity curve will eventuate, although this too can take a long time to happen. Try a nonzero value of prob.of.mutate with monoculture start (use individually=FALSE for such experiments)
突变的概率。零对应的默认theta=0，这意味着任何生态系统最终将成为一个单一文化（这是特别有启发性看这种情况，尤其是在一个生态系统中最大的多样性: 但被警告，这可能需要很长的时间，特别是对大量个人）的生态系统。非零值的意思是，一个平凡的优势多样性曲线会落空，虽然这也需要很长的时间才发生。与单作启动（使用prob.of.mutate这样的实验，尝试一个非零值individually=FALSE）
参数：cex
The size of the dots used for plotting, defaulting to 3
用于绘制的点的大小，缺省值为3
参数：individually
Boolean, with default TRUE meaning that a timestep means the death of a single individual and the simultaneous birth of a new individual; and FALSE meaning that a timestep refers to every individual in the system
布尔，默认TRUE，这意味着一个时间步长是指一个单一的个体，同时诞生了一个新的个体的死亡和FALSE的意思，时间步长是指系统中的每一个人
参数：ask
Boolean, with default FALSE meaning to display the generations autonomously, and TRUE meaning to wait for the user to hit the “return” before proceeding
布尔默认情况下，与FALSE意思显示的后代，自主，TRUE的这意味着等待用户，然后再继续打的“回报”
参数：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. Use TRUE for pedagogic purposes, possibly with ask set to TRUE, or a nonzero delay. This option only kicks in if individually is TRUE
布尔值，TRUE意思表示站点的一个死亡/出生闪烁的环的默认FALSE的这意味着省略闪烁的环。使用TRUE教学的目的，，可能与ask设置为TRUE，或非零delay。此选项仅踢如果individually是TRUE的
参数：delay
Time delay between generations in seconds; meaningful whatever the value of flash and individually
有意义的任何值的flash和individually之间的时间延迟以秒为单位的世代;
参数：cols
A vector of colours with default NULL meaning to choose them randomly. Useful for printing stills from a movie
默认NULL的这意味着选择随机颜色的矢量。可用于打印的电影剧照
参数：...
Further arguments passed to plot() and points()
更多参数传递给plot()和points()
