Relatively inexperienced R user here. I'm trying to analyze baseball games from the top five exit velocities of each one using the code below (with 1 being the highest downward).

SavantEV2 = SavantEV %>% 
  group_by(game_date, home_team, away_team) %>% 
  summarise(
    EV1 = nth(launch_speed, 1, descending = T),
    EV2 = nth(launch_speed, 2, descending = T),
    EV3 = nth(launch_speed, 3, descending = T),
    EV4 = nth(launch_speed, 4, descending = T),
    EV5 = nth(launch_speed, 5, descending = T)
  )

Everything's been going swimmingly thus far, but I want to find a way to associate each exit velocity with the team/player that hit it. I have another data frame below that I figure I could use to accomplish this.

Data frame with every exit velocity from last season

If anyone knows any functions I could use to add this data that would be amazing. Thank you for going through my little spiel here too. Cheers!

  • Operations to associate two data frames are called "joins" - have a look at [this R-FAQ on joins](https://stackoverflow.com/q/1299871/903061). – Gregor Thomas Apr 14 '22 at 02:28
