Returns a Seurat object with VariableFeatures set to the randomly sampled features.

Examples

DownsampleFeatures(atac_small, n = 10)

#> Randomly downsampling features
#> An object of class Seurat 
#> 1323 features across 100 samples within 3 assays 
#> Active assay: peaks (323 features, 10 variable features)
#>  2 other assays present: bins, RNA
#>  2 dimensional reductions calculated: lsi, umap
