Examples

# NOT RUN {
library(dplyr)
# We create some cluster from k-means on the iris data set
data <- iris %>% select(Sepal.Length, Sepal.Width, Petal.Length, Petal.Width)
result_kmeans <- kmeans(data, 3)
data$cluster <- result_kmeans$cluster
# We get the coordinates of the centroid of the second cluster
result <- cluster_centroid(i = 2, data = data, cluster_variable = "cluster")
result
# }
