我有多个数据框,但它们都有相同的列标题我想要做的只是一个接一个地附加它们以制作一个大数据框。做这个的最好方式是什么。

我使用了以下方法:但不确定这是正确的方法:

append(x, y)

我也尝试了 rbind 但最终出现以下错误,因为这些数据帧的大小不同:

Error in names(value[[jj]])[ri] <- nm : 
  'names' attribute [2066] must be the same length as the vector [9]
In addition: Warning message:
In names(value[[jj]])[ri] <- nm :
  number of items to replace is not a multiple of replacement length

这是一个例子:

> x
  user_id rev_page   rev_id rev_parent_id page_ns rev_length delta deleted rev_curr_minor           timestamp edit_count lang_level

如果列的顺序相同(遵循@MatthewPlourde 的评论),只需rbind(df1,df2,df3,...).
