我在Windows 8机器上出现随机林和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？filter.featuresTrain是一个具有12行104列的数据框。并非我所有的列都被命名。可能是问题吗？（我仅包含12行，因为dput的大小对于发布而言太大。）
感谢您的帮助！这是我的代码：数据集位于末尾

看来您有一些异常的列名称，例如
..6, ..12.2, ..6.2, etc
虽然在技术上有效，但似乎randomForest()不喜欢它们。最简单的方法是只重命名以双句号开头的那些列。在这里，我用“ V”代替它们。
names(filtered.featuresTrain)<-gsub("^\\.\\.", "V.",
names(filtered.featuresTrain))
这至少应消除以下错误： eval()
