Function clusplot assign color to dots depending on a added column-CodePudding

I used k-means for clustering after that I plotted my clusters with the clusplot function. I know you can color code the dots depending on the cluster. But I want to color code them depending on a separate column, which just includes “yes” or “no”. I added this column to my data frame after the clustering.

Does anyone have an idea?

Thank you so much in advance.

Here is an example using the iris data set that comes with R:

library(cluster)
data(iris)
iris.clara <- clara(iris[, -5], 3)
set.seed(42)   # Set random seed for replicability
code <- sample(c("Yes", "No"), 150, replace=TRUE)
color <- ifelse(code=="Yes", "red", "blue")
clusplot(iris.clara, col.p=color)
