Compute variance explained by PCA, given a Seurat object for which the PCA dim. reduction has been calculated
getVarianceExplained(seurat, n = 10)
| seurat | Seurat object |
|---|---|
| n | Numeric, number of PCs for which variance should be reported. Default: 10 |
List with two vectors, "percent.var.explained" and "cumulative.var.explained",
reported for the first n PCs
