In SeuratObject: Data Structures for Single Cell Data

Create a DimReduc object

Description

Create a DimReduc object

Usage

CreateDimReducObject(
  embeddings = new(Class = "matrix"),
  loadings = new(Class = "matrix"),
  projected = new(Class = "matrix"),
  assay = NULL,
  stdev = numeric(),
  key = NULL,
  global = FALSE,
  jackstraw = NULL,
  misc = list()
)

Arguments

embeddings	A matrix with the cell embeddings
loadings	A matrix with the feature loadings
projected	A matrix with the projected feature loadings
assay	Assay used to calculate this dimensional reduction
stdev	Standard deviation (if applicable) for the dimensional reduction
key	A character string to facilitate looking up features from a specific DimReduc
global	Specify this as a global reduction (useful for visualizations)
jackstraw	Results from the JackStraw function
misc	list for the user to store any additional information associated with the dimensional reduction

Value

A DimReduc object
