AddMetaData: Add in metadata associated with either cells or features.

In mojaveazure/seurat-object: Data Structures for Single Cell Data

Add in metadata associated with either cells or features.

Description

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 class 'Assay'
AddMetaData(object, metadata, col.name = NULL)

## S3 method for class 'Assay5'
AddMetaData(object, metadata, col.name = NULL)

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

Arguments

object	An object
metadata	A vector, list, or data.frame with metadata to add
col.name	A name for meta data if not a named list or data.frame

Value

object with metadata added

Examples

cluster_letters <- LETTERS[Idents(object = pbmc_small)]
names(cluster_letters) <- colnames(x = pbmc_small)
pbmc_small <- AddMetaData(
  object = pbmc_small,
  metadata = cluster_letters,
  col.name = 'letter.idents'
)
head(x = pbmc_small[[]])
