Get the PCA singular values

Returns the PCA singular values (can be useful to assess cumulative variance explained). This function is used for the single cell-related classes and methods.

Usage

get_pca_singular_val(x, ...)

## S7 method for class <bixverse::MetaCells>
get_pca_singular_val(x, ...)

# S3 method for class 'ScCache'
get_pca_singular_val(x, ...)

## S7 method for class <bixverse::SingleCells>
get_pca_singular_val(x, ...)

## S7 method for class <bixverse::SingleCellsSubset>
get_pca_singular_val(x, ...)

Arguments

x

An object to get PCA singular values from.

...

Other parameters.

Value

The PCA singular values from the object (if found).

Examples

# singular values, largest first
sc <- demo_single_cells()
head(get_pca_singular_val(sc), 3)
#> [1] 47.75282 44.16640 25.33718
