Get default dimension reduction for Seurat object
Arguments
- object
Seurat object to query
Value
Name of the default dimension reduction, or NULL if not set
Details
DefaultDimReduc was just introduced in Seurat v5.4.0.
This function will first check if we have DefaultDimReduc value in the misc slot (set by our fallback setter),
and if not, it will try to call the official DefaultDimReduc getter function. If that also fails, it will return NULL.
