kmeans()

print(lineup)

       x     y
 1    -1     1
 2    -2    -3
 3     8     6
 4     7    -8
 ...  ...   ...

model <- kmeans(lineup, centers = 2)

Assigning clusters

print(model$cluster)

1 1 2 2 1 1 1 2 2 2 1 2

lineup_clustered <- mutate(lineup, cluster = model$cluster)
print(lineup_clustered)

       x     y cluster
   <dbl> <dbl>   <int>
 1    -1     1       1
 2    -2    -3       1
 3     8     6       2
 4     7    -8       2
 ...  ...  ...     ...

Let's practice!
