我试图根据我从其他数据框创建的列表来弄清楚如何保留数据帧的行。我已经查看了其他几个解决此问题的问题，并尝试了建议的代码（R- keep dataframe rows only if the row name is in a list，Select rows in a dataframe in r based on values in one row），但代码并不适用于我。我确定这是一个简单的错误，但我无法弄清楚它是什么。
我试过的一个代码：
A <- AllSiteBA[AllSiteBA$Cofecha %in% keeps,]
输出（没有任何匹配......当我运行整个AllSiteBA data.frame时，应该有76个匹配）：
> A
[1] Cofecha DBHinBark RBHinBark BAtotal MeanBAww PercentBAww
[7] Plot
<0 rows> (or 0-length row.names)
我尝试过的另一个代码：
A＆lt; - subset（AllSiteBA，Cofecha％in％keep）
与我尝试过的第一个代码完全相同。
任何有关如何修复代码的帮助将不胜感激。下面是我的data.frame和list的可重现部分。
