runCluster(
  object,
  cluster.method = c("som", "kmeans", "clara", "phenograph", "hclust", "mclust"),
  verbose = FALSE,
  ...
)

Arguments

object

a CYT object

cluster.method

character. Four clustering method are provided: som, clara, kmeans and phenograph. Clustering method "hclust" and "mclust" are not recommended because of long computing time.

verbose

logic. Whether to print calculation progress.

...

options to pass on to the clustering functions.

Value

A CYT object with cluster

See Also

SOM, hclust, clara, kmeans. You can use runSOM, runClara, runPhenotype, runKmeans, runMclust and runHclust to run clustering respectively.

cyt <- runCluster(cyt, cluster.method = "phenograph", verbose = TRUE)

# hclust clustering
# not recommended for large cell size

# mclust clustering
# not recommended for large cell size
cyt <- runCluster(cyt, cluster.method = "mclust", verbose = TRUE)
