Normalization

K-means clustering with 10 clusters

set.seed(1234) KmeansClustering = kmeans(hubwaytripNorm, centers = 10)

Examination of results

table(KmeansClustering$cluster) tapply(hubwaytrip$Duration, KmeansClustering$cluster, mean) tapply(hubwaytrip$Morning, KmeansClustering$cluster, mean) tapply(hubwaytrip$Afternoon, KmeansClustering$cluster, mean) tapply(hubwaytrip$Evening, KmeansClustering$cluster, mean) tapply(hubwaytrip$Night, KmeansClustering$cluster, mean) tapply(hubwaytrip$Weekday, KmeansClustering$cluster, mean) tapply(hubwaytrip$Weekend, KmeansClustering$cluster, mean) tapply(hubwaytrip$Male,KmeansClustering$cluster, mean) tapply(hubwaytrip$Age, KmeansClustering$cluster, mean)

Visualiseing the clusters

install.packages('ggpubr') library(ggpubr) install.packages('factoextra') library(factoextra) fviz_cluster(KmeansClustering, data = hubwaytrip, geom = "point", ellipse.type = "convex", ggtheme = theme_bw() )

fviz_cluster(KmeansClustering, data = hubwaytrip, geom = "point", ellipse.type = "euclid", ggtheme = theme_bw() )
