Reading in multiple files to append them is quite common in my field. Let’s go through a couple ways you can do that in R.

I enjoyed this post!

I learned something new: that read_csv can take a vector of filenames and return the dataframes all glued together.

I think you can also use bind_rows on the output from lapply (it will take a list of dataframes), though that is a rather odd base + tidyverse mix.

yes, when I saw that I was so amazed! I think it was something Jenny Bryan mentioned in passing related to something else and my head exploded a little :P

Using bind_rows is a great option to swap in for rbind if the files dont have the exact same columns for some reason. I've done this before when a condition was added to the data a little into data collection, and then rbind would fail.
