Convert objects to GraphSpace

Source: R/gspace-coercion.R
as.GraphSpace.Rd

S3 generic function for coercing objects into a GraphSpace object.

Usage

as.GraphSpace(x, ...)

# Default S3 method
as.GraphSpace(x, ...)

# S3 method for class 'igraph'
as.GraphSpace(x, ...)

# S3 method for class 'tbl_graph'
as.GraphSpace(x, ...)

# S3 method for class 'data.frame'
as.GraphSpace(x, ...)

# S3 method for class 'Seurat'
as.GraphSpace(x, space = c("embedding", "spatial"), layer = NULL, ...)

Arguments

x

An object to be converted.

...

Additional arguments passed to methods associated with the selected space.

space

Character specifying the coordinate space used for node geometry. Either "embedding" or "spatial". See details.

layer

Name of the layer from which node data should be retrieved (see LayerData).

Value

A GraphSpace object.

Details

Unified entry point for converting graph, spatial, and high-dimensional data into a GraphSpace object.

Graph objects are imported either through native methods or via as_tbl_graph when available.

For Seurat objects, coordinate extraction depends on the selected space:

  • space = "embedding" uses the first two dimensions returned by Embeddings.

  • space = "spatial" uses tissue coordinates returned by GetTissueCoordinates.

Assay data are stored in the data slot of the resulting GraphSpace object. Node metadata from x@meta.data are appended to the node table.
