getCls: get base clustering results using SC3 based clustering...

In DrImpute: Imputing Dropout Events in Single-Cell RNA-Sequencing Data

Description

Similarity matrix constructed using "pearson", "spearman" or "euclidean". K-means clustering is performed on first few number of principal components of similarity matrix.

Usage

getCls(X, ks = 10:15, dists = c("spearman", "pearson"),
  dim.reduc.prop = 0.05)

Arguments

X	Log transformed gene expression matrix (Gene by Cell).
ks	Number of cell clustering groups. Default set to ks = 10:15.
dists	Distribution matrices to use. Default is set to c("spearman", "pearson"). "euclidean" can be added as well.
dim.reduc.prop	Proportion of principal components to use for K-means clustering.

Value

A matrix object, Each row represent different clustering results.
