Add Gene-Level Metadata to Seurat Object (Vectorized, ...-based)

Source: R/50-AddMetaFeature.R
AddMetaFeature.Rd

Add multiple feature-level metadata (vectors or 2D tables) to a Seurat object. Handles vectors (length-checked), matrices, data.frames, data.tables, etc. Columns/variables with duplicated names are suffixed (e.g., "type_1"). Gene alignment is auto-detected: rows or cols must match nrow(seurat_obj).

Usage

AddMetaFeature(seurat_obj, ..., assay = "RNA")

Arguments

seurat_obj

A Seurat object.

...

One or more metadata inputs:

  • Named/unnamed vectors (length = ngenes)

  • 2D objects (matrix, data.frame, data.table, etc.) where one dimension (rows or cols) has size = ngenes.

assay

Assay name (default: "RNA", fallback to first).

Value

Modified seurat_obj (invisibly).
