Supplement 1. Two files for fitting binomial mixture models as described originally by Royle (2004).

File List Supplement 1, original Nmixture.R -- R source code. Nmixture_tutorial.txt -- A step by step description of how to use the R code in file "Nmixture.R". Supplement 1, Revision 1 Nmixture.R -- R source code, corrected. Description This supplement provides the file "Nmixture.R" which can be sourced into R. It contains example data for one species and code to fit Poisson and Negative Binomiol mixture models as described in Royle (2004) and in this article.附录1 文件列表 原始Nmixture.R——R语言源代码文件 Nmixture_tutorial.txt——分步详细说明如何使用"Nmixture.R"中的R代码 修订版1 Nmixture.R——经修正后的R语言源代码文件 说明 本附录提供可在R环境中加载运行的"Nmixture.R"文件，内含单物种示例数据，以及用于拟合Royle（2004）及本文所述的泊松（Poisson）与负二项（Negative Binomial）混合模型的代码。
