我在Windows 8计算机上遇到随机林和Rstudio的错误：
Error in eval(expr, envir, enclos) :
..6 used in an incorrect context, no ... to look in
我做错了什么？ filtered.featuresTrain是一个包含12行和104列的数据帧。并非所有列都已命名。可能是问题吗？ （我只包含12行，因为dput的大小对于发布来说太大了。）
感谢您的帮助！ 这是我的代码：数据集在最后

答案 0 :(得分：2)
您似乎有一些不寻常的列名，如
..6, ..12.2, ..6.2, etc
虽然技术上有效但似乎randomForest()不喜欢它们。最简单的方法是重新命名以双周期开头的列。在这里，我用“V”替换它们。
names(filtered.featuresTrain)<-gsub("^\\.\\.", "V.",
names(filtered.featuresTrain))
这至少应该消除eval()
