Profiling k-Prototypes Clustering
Visualization of a k-prototypes clustering result for cluster interpretation.
clprofiles(object, x, vars = NULL, col = NULL)
object |
Object resulting from a call of resulting |
x |
Original data. |
vars |
Optional vector of either column indices or variable names. |
col |
Palette of cluster colours to be used for the plots. As a default RColorBrewer's
|
For numerical variables boxplots and for factor variables barplots of each cluster are generated.
