Source: R/stat_kmeans.R
plot.stat_kmeans.Rd

Visualize k-means clustering with various plot types.

Usage

# S3 method for class 'stat_kmeans'
plot(x, type = c("clusters", "withinss"), color = NULL, labels = NULL, ...)

Arguments

x

A stat_kmeans object

type

Character. Type of plot:

  • "clusters": Cluster visualization (requires PCA projection)

  • "withinss": Within-cluster sum of squares by cluster

color

Column name (bare or quoted) for coloring points (for cluster plot). If NULL, colors by cluster assignment.

labels

Column name (bare or quoted) for text labels.

...

Additional arguments (reserved)

Value

NULL (invisibly). Draws plot as side effect.

Examples

if (FALSE) { # \dontrun{
km <- boteft %>% stat_kmeans(k = 3)

# Cluster plot (colored by cluster)
plot(km)

# Color by original grouping
plot(km, color = type)

# Within-cluster SS plot
plot(km, type = "withinss")
} # }
