我有多个数据框，但它们都有相同的列标题我想要做的就是一个接一个地追加它们以制作一个大的数据帧。什么是最好的方法。
我使用了以下内容：但不确定这是正确的方法：
append(x, y)
我也尝试了rbind，但最终出现了我预期的错误，因为这些数据框的大小不同：
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
以下是一个例子：
> x
user_id rev_page rev_id rev_parent_id page_ns rev_length delta deleted rev_curr_minor timestamp edit_count lang_level

答案 0 :(得分：1)
如果列的顺序相同（在@ MatthewPlourde的评论之后），只需rbind(df1,df2,df3,...)。
