How do I replace specific values in dataframe colum with other specific values through a loop in R

I am trying to replace specific values in a data frame with specific values through a loop. I am kinda new to the world of R but I am a bit stuck:

top200$track.id[top200$track.id == "7ytR5pFWmSjzHJIeQkgog4"] <-
  "4Aykm3xrOFSHrAnv80KUhh"
top200$track.id[top200$track.id == "6thXB4RmajS4oZPNiBAKy0"] <-
  "3m0y8qLoznUYi73SUBP8GI"
top200$track.id[top200$track.id == "6OqrJqDMu15AGJHJazg9Nr"] <-
  "463CkQjx2Zk1yXoBuierM9"
top200$track.id[top200$track.id == "1rgnBhdG2JDFTbYkYRZAku"] <-
  "5ZULALImTm80tzUbYQYM9d"
top200$track.id[top200$track.id == "3apeXzypBMnUfYcZYNX6DH"] <-
  "37ZtpRBkHcaq6hHy0X98zn"
top200$track.id[top200$track.id == "6gBFPUFcJLzWGx4lenP6h2"] <-
  "2SzjMcZIsE2zUWQnccsTAo"
top200$track.id[top200$track.id == "513JwqDfENCJ0Woi0T42qy"] <-
  "6hci8n9UowepjRmCc6CKTv"
top200$track.id[top200$track.id == "13vDU8nPsvTGEVTMB8Vw7g"] <-
  "6AzKhCHOms83jvNVLsz0Bt"
top200$track.id[top200$track.id == "30VrBsh1STRBoIrhQOAwzK"] <-
  "2VOomzT6VavJOGBeySqaMc"
top200$track.id[top200$track.id == "79s5XnCN4TJKTVMSmOx8Ep"] <-
  "6PnTgx9lyvLGIcPnroCvc2"
top200$track.id[top200$track.id == "6i7zAdNhzUN2k1HcrBxPHG"] <-
  "14ngWWxvUSnIMXgF6rzSk1"
top200$track.id[top200$track.id == "1RSzyxqtIO4yX3EyiV4zT5"] <-
  "5vGLcdRuSbUhD8ScwsGSdA"
top200$track.id[top200$track.id == "4u7EnebtmKWzUH433cf5Qv"] <-
  "7tFiyTwD0nx5a1eklYtX2J"
top200$track.id[top200$track.id == "0jT8Nl0shPS8115is0wD2Q"] <-
  "0Snbzbd74RLfL0i4nn1vU5"
top200$track.id[top200$track.id == "3xgT3xIlFGqZjYW9QlhJWp"] <-
  "6Qs4SXO9dwPj5GKvVOv8Ki"
top200$track.id[top200$track.id == "24IgCW19L8lXKyFZwzFtD3"] <-
  "14wf185UxfNbSy8dwt4r4q"
top200$track.id[top200$track.id == "2xLMifQCjDGFmkHkpNLD9h"] <-
  "0u695M7KyzXaPIjpEbxOkB"

This is what I got so for looking at other examples, but it is still not really working. Any suggestions on how to do this?

for i in top200$track.id {
  if top200$track.id[i] %in% old_values {
    old_values[i] <- new_values[i]
  }
}
