本文简要介绍了用于进行考试抄袭识别的R软件的CopyDetect包，描述了CopyDetect所提供的考试抄袭识别指标ω、GBT、K指数及K系列指数的含义，并使用模拟数据对CopyDetect如何进行考试抄袭识别进行了实例操作分析。比较了在不同比例的雷同卷中，CopyDetect包的不同指数识别的灵敏度。最后，指出了CopyDetect包存在的不足和需要针对我国考试作弊实际情况进行修订的地方。

In this article, we briefly described the CopyDetect package for R software. This package was designed for computing statistical indices to Detect answer copying on multiple-choice examinations. The ω index, Generalized Binomial Test(GBT), K index and K variants were introduced and simulated data was analyzed by CopyDetect package. We used CopyDetect package to compare the different percentage answer copying. The results of different p-value of different indices indicated different sensitivity of these indices. Finally, we discussed the shortages of CopyDetect package and believed it was needed revised for adapting answer copying style in China.
