You could be interesting in this book to get more used to how data manipulation can be achieved efficiently

Some pointers with dplyr

  • you can add columns using mutate()
  • you can rename you column using rename()

You can do many other thing to prepare you data.

You can get access to tutorials too:

Look at Rstudio Primers for example.

Hope it helps.
