描述----------Description----------
get.groups generates input for bd.shifts.optim if the phylogeny is not resolved on the species level (groups!=0)
get.groups产生输入系统发育的bd.shifts.optim如果不解决在种的水平(groups! = 0)
用法----------Usage----------
get.groups(tree,S,xcut=0)
参数----------Arguments----------
参数:tree
phylogenetic tree to be analyzed with bd.shifts.optim
要与bd.shifts.optim分析系统进化树
参数:S
S[i]: Number of species in tree represented by leaf i
S [我]:种数表示在树的叶我
参数:xcut
Age of the higher taxa. If xcut=0: age of higher taxa is the length of the edge corresponding to the higher taxa. If xcut>0: age of each higher taxa is xcut
年龄较高的类群。如果xcut = 0:年龄较高级分类单元是对应于较高的分类单元的长度的边缘。如果> 0 xcut:年龄每一个较高级分类单元是xcut的
