AddMetaData

0th

Percentile

Add in metadata associated with either cells or features.

Adds additional data to the object. Can be any piece of information associated with a cell (examples include read depth, alignment rate, experimental batch, or subpopulation identity) or feature (ENSG name, variance). To add cell level information, add to the Seurat object. If adding feature-level metadata, add to the Assay object (e.g. object[["RNA"]]))

Usage
AddMetaData(object, metadata, col.name = NULL)

# S3 method for Assay AddMetaData(object, metadata, col.name = NULL)

# S3 method for Seurat AddMetaData(object, metadata, col.name = NULL)

# S4 method for Assay [[(x, i, j, ...) <- value

# S4 method for Seurat [[(x, i, j, ...) <- value

Arguments
x, object

An object

i, col.name

Name to store metadata or object as

j

Ignored

...

Arguments passed to other methods

value, metadata

Metadata or object to add

Value

An object with metadata or and object added
