Create a downsampled copy of a ScPhyloExpressionSet object with fewer cells per identity.
Usage
downsample(phyex_set, downsample = 10)
Arguments
- phyex_set
A ScPhyloExpressionSet object
- downsample
Integer, number of cells to keep per identity (default: 10)
Value
A new ScPhyloExpressionSet object with downsampled cells
Details
This function creates a new ScPhyloExpressionSet with a subset of cells, maintaining
the same proportional representation across identities. The sampling is stratified
by the current selected_idents grouping. All metadata and reductions are
filtered to match the selected cells.
Examples
if (FALSE) { # \dontrun{
# Downsample to 20 cells per identity
small_set <- downsample(sc_phyex_set, downsample = 20)
# Change grouping and downsample
sc_phyex_set@selected_idents <- "treatment"
treatment_set <- downsample(sc_phyex_set, downsample = 15)
} # }
