问题
Have 68 data frames with the same structure and columns. I started to use rbind and after typing in about 30 df names, I thought there might be an easier way to concatenate all the data frames without typing in each name. I mean, what if you have 100,000 data frames to concatenate? I looked at a dozen of online resources including this site and didn't find exactly what I was looking for.
All the 68 data frames are named sequentially. For example: df_01, df_02, ... up to df_68. I tried to do rbind(df_01:df_68) and of course this did not work.
