Arguments

cluster_labels: list of cluster labels, automatically converted to factor.
long: if TRUE, returned data frame will be in long format. See details for spec. Default is TRUE.
selected_clusters: optional cluster labels to filter

Value

a wide or long data frame

Details

Long data frame will have columns: Cluster, Measurement and Value.

Examples

dmat <- compute_dmat(iris, "euclidean", TRUE, c("Petal.Length", "Sepal.Length"))
res <- compute_clusters(dmat, "complete")
cluster_labels <- cut_clusters(res, 2)
annotated_data <- annotate_clusters(iris[, c("Petal.Length", "Sepal.Length")], cluster_labels)
head(annotated_data)
