Answer by Sal-laS for What can R do about a messy data format?

Well, about this specific dataset I used the import feature in RStudio, but I took one additional step beforehand.

1. Copy the dataset into the Notepad file.
2. Replace all | characters with ,
3. Import the Notepad file using read.csv to RStudio using this code (seperate columns by ,).

But, if you mean use the R to fully understand it in one step, then I have no idea.
