Get global spatial analysis results and metadata of colData, rowData, and geometries

Results of spatial analyses on columns in colData, rowData, and geometries are stored in their metadata. The colFeaturedata function allows the users to more directly access these results.

Usage

colFeatureData(sfe)

rowFeatureData(sfe)

geometryFeatureData(sfe, type, MARGIN = 2L)

reducedDimFeatureData(sfe, dimred)

Arguments

sfe

An SFE object.

type

Which geometry, can be name (character) or index (integer)

MARGIN

Integer, 1 means rowGeometry, 2 means colGeometry, and 3 means annotGeometry. Defaults to 2, colGeometry.

dimred

Name of a dimension reduction, can be seen in reducedDimNames.

Value

A DataFrame.
