回答：任一列中的单个 NA 值都data.frame可能导致此错误。
我有一个相当令人沮丧的问题需要帮助。我正在尝试在 R 中运行 permanova，并且我正在使用adonis()Vegan 来执行此操作。我有一个按样本的物种data.frame，249 行 x 16 列（物种名称为column.names），以及一个单独data.frame的 249 行 x 3 列，包含我的环境协变量。我使用下面的代码来运行它，我得到了上面的错误。我在一些非常非常相似的数据上运行 adonis 没有问题，我不确定这次出了什么问题。
有什么建议么？万分感谢。
代码
SpeciesADONIS <- adonis(ScreenedSpeciesbySample ~ AvgSalinity + AvgTurbidity +
AvgDO + AvgSalinity * AvgTurbidity + AvgSalinity*AvgDO +
AvgTurbidity * AvgDO,
data = RegPhysDriversTimeSeries2,
permutations=999, method="bray")
