合并数据帧列表并使用NA.omit（do.call（merge，x））删除NA
我有一个从定义函数返回的数据帧列表，如下所示：合并数据帧列表并使用NA.omit（do.call（merge，x））删除NA,r,R,我有一个从定义函数返回的数据帧列表，如下所示： [[1]] NA [[2]] JPY.CLOSE JPY.CLOSE.1 EMA 2017-02-23 -0.5150519 -1.962526 44.07448 为了纠正这一点，我使用了以下代码： na.omit(do.call(merge, ret)) out.trend <- matrix(new.trend(MergedData), ncol = 3, byrow = TRUE, dimna
[[1]]

您好：需要初始数据和您所做的更改来给出任何类型的答案。正如@ike所说的，更多的数据会有所帮助。您也可以尝试使用l=l[！sapply（l，is.null）]删除您的列表NA@ike无法真正给出初始更改，因为数据来自Excel。我在Excel中添加了其他列。附加了初始数据，以及我用来转换它的代码以及返回问题列表的代码。@B Williams这是用来删除NA的。我现在正试图找到一种方法，将我的列表压缩成一个我想通过HTML输出的表。编辑我的问题，谢谢！基本上，你的错误看起来像是当你有不连贯的行时弹出的类型，因此你在一个段中有100个，在另一个段中有200个，而r在寻找完整的案例；如果它用完了，那么公式就失效了。
