Seurat (version 3.1.4)

AddMetaData: 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 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

# NOT RUN {
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[[]])
