Fetch Cell-Level Data from a Seurat Object — fetch_cell

Extracts a tidy tibble with one row per cell containing cell identifiers, optional dimensionality reduction embeddings, and optional metadata. No expression data is included — use fetch_feature_data for that.

Usage

fetch_cell_data(object, reductions = NULL, dims = 1:2, metadata = TRUE)

Arguments

object: Seurat object.
reductions: character. Reduction names to include (default: NULL = none). Example: c("umap", "pca").
dims: integer. Dimensions to extract per reduction (default: 1:2).
metadata: logical or character. TRUE = all metadata columns, FALSE = none, or a character vector of specific column names.

Value

A tibble with columns: cell_id, optional embedding columns, and optional metadata columns.

Examples

if (FALSE) { # \dontrun{
# All metadata, no embeddings
fetch_cell_data(seurat_obj)

# With UMAP coordinates
fetch_cell_data(seurat_obj, reductions = "umap")

# Specific metadata + PCA
fetch_cell_data(seurat_obj, reductions = "pca", dims = 1:10,
                metadata = c("seurat_clusters", "condition"))
} # }
