thank you for this Matt. Can we use nesting instead of group by and group split? in this example for writing mutliple files? tryiing to get it the idea working

thanks for the video matt. just wondering about the [.f] iterable for the map call. wondering if that is getting the data in the pipe chain? is [.f] arbitrary or does it have to be that canonically can it be [.j] for instance?

No need to bind rows, simply use map_df instead whean reading the files...

I have a query: I want R to read multiple files but not all in the folder -> transpose them -> extract col 1 of each of those transposed files -> paste it into separate columns in completely new single file. Kindly help.

PS (if you don't mind) video quality: on laptop/tablet or below 720p is kind of difficult to read it 👴
