reduceDimension: Computes a projection of a CellDataSet object into a lower dimensional space

Description

Computes a projection of a CellDataSet object into a lower dimensional space

Usage

reduceDimension(cds, max_components = 2, use_irlba = TRUE,
  pseudo_expr = 1, batch = NULL, covariates = NULL, ...)

Arguments

cds
the CellDataSet upon which to perform this operation
max_components
the dimensionality of the reduced space
use_irlba
Whether to use the IRLBA package for ICA reduction.
pseudo_expr
amount to increase expression values before dimensionality reduction
batch
a vector of labels specifying batch for each cell, the effects of which will be removed prior to dimensionality reduction.
covariates
a numeric vector or matrix specifying continuous effects to be removed prior to dimensionality reduction
...
additional arguments to pass to the dimensionality reduction function

Value

  • an updated CellDataSet object

Details

Currently, Monocle supports dimensionality reduction with Independent Component Analysis (ICA).
