Seurat (version 5.0.3)

RunGraphLaplacian: Run Graph Laplacian Eigendecomposition

Description

Run a graph laplacian dimensionality reduction. It is used as a low dimensional representation for a cell-cell graph. The input graph should be symmetric

Usage

RunGraphLaplacian(object, ...)

# S3 method for Seurat RunGraphLaplacian( object, graph, reduction.name = "lap", reduction.key = "LAP_", n = 50, verbose = TRUE, ... )

# S3 method for default RunGraphLaplacian(object, n = 50, reduction.key = "LAP_", verbose = TRUE, ...)

Value

Returns Seurat object with the Graph laplacian eigenvector calculation stored in the reductions slot

Arguments

object

A Seurat object

...

Arguments passed to eigs_sym

graph

The name of graph

reduction.name

dimensional reduction name, lap by default

reduction.key

dimensional reduction key, specifies the string before the number for the dimension names. LAP by default

n

Total Number of Eigenvectors to compute and store (50 by default)

verbose

Print message and process
