fviz_cluster - possible to manually assign colors to clusters?

[Sadia Haider]

I am running HCPC after MCA and would like to manually assign colors to my 3 clusters ("darkgreen" for cluster 1, "orange" for cluster 2, "red" for cluster 3) . Please could you tell me if this is possible using fviz_cluster? Many thanks!

Hi Sadia,

since factoextra is build upon ggplot2, this is no problem:

library(FactoMineR)

library(factoextra)

data(tea)

res_mca <- MCA(tea[, 1:5], graph = FALSE)

res_hcpc <- HCPC(res_mca, nb.clust = 3, graph = FALSE)

fviz_cluster(res_hcpc, ) +

  scale_colour_manual(values = c("darkgreen", "orange", "red")) +

  scale_fill_manual(values = c("darkgreen", "orange", "red")) 

All the best,

Fabian
