Source code for partitioning live-dead variation in taphonomic analyses

Source code (R language) for partitioning of total live-dead compositional variation among multiple living (individuals sampled alive) and death assemblages (individuals collected as dead) into variation caused by (1) sampling and biological variation among living assemblages and (2) new variation that arises from postmortem taphonomic processes. The balanced design is required, i.e., the same number of living and death assemblages sampled in the same (homogeneous) habitat.用于将多个现生组合（即采样时仍存活的个体，living assemblages）与死亡组合（即采集获得的已死亡个体，death assemblages）之间的总存活-死亡组成变异，拆分为两类成因的R语言源代码：(1) 现生组合间的采样与生物学变异；(2) 死后埋藏学（taphonomic）过程引发的新增变异。本方法要求采用均衡设计，即需在相同的均质生境中采集等量的现生组合与死亡组合。
