R Merge Dataframe

Question

I have multiple data frames but they all have same column headers what I want to do is just append them one after the other to make one big dataframe. What is the best way to do this.

I used the following: but not sure this is the right way to do:

append(x, y)

I also tried rbind but ended up with following error as I expected since these data frames have different length in size:

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

Here is an example:

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

Answer 1

If columns are in the same order (following @MatthewPlourde's comment), just rbind(df1,df2,df3,...).
