Adds arbitrary data to the @misc slot of a Seurat object with automatic key
conflict resolution. If the key already exists, automatically appends a numeric
suffix to ensure unique key naming (e.g., "mykey_1", "mykey_2").
Usage
AddMisc(
seurat_obj,
..., # key = value
cover = TRUE # overwrite existing data
)
Arguments
- seurat_obj
A Seurat object to modify
- ...
key-value pairs to add to the @misc slot.
- cover
Logical indicating whether to overwrite existing data. If
(default TRUE).
Value
The modified Seurat object with added @misc data. The original object
structure is preserved with no other modifications.
Key Generation Rules
If key doesn't exist: uses as-is
If key exists: appends the next available number (e.g., "key_1", "key_2")
If numbered keys exist (e.g., "key_2"): increments the highest number
Examples
if (FALSE) { # \dontrun{
# Basic usage
seurat_obj <- AddMisc(seurat_obj, "QC_stats" = qc_df)
# Auto-incrementing example
seurat_obj <- AddMisc(seurat_obj, markers = markers1)
seurat_obj <- AddMisc(seurat_obj, markers = markers2, cover=FALSE)
# Stores as "markers" and "markers_1"
} # }
