我今天安装了最新的软件包，并将所有演示版本运行到luxor.8。其他一切都很好但是luxor.8仍然有如下错误：
Error in runSum(x, n) : Invalid 'n'
In addition: Warning messages:
1: In beg:(n + beg - 1) :

2: In 1:(n - 1 + NAs) :

我注意到最新包中luxor.8产生的错误与the error generated in previous version of the package不同。因此，我假设这个最新版本的软件包解决了luxor.8中的先前错误。如果是这样，我报告的错误应该是微不足道的，对吗？
有人能就我上面报道的错误给我一些建议吗？感谢
