## Factorization measures in an Object

### Description

Retrieve or set factorization measures in an object

### Usage

    measure(object)

### Arguments

`object` | Object of class `scNMFSet`.

### Details

Factorization under multiple rank values lead to measures stored in a data frame inside a slot `measure`. In maximum likelihood using `factorize`, this set of quality measures include dispersion and cophenetic coeeficients for each rank. In Bayesian factorization using `vb_factorize`, log evidence for each rank is stored. `measure(object)` will return the data frame. `measure(object) <- value` can be used to modify it.

### Value

Either `NULL` or a data frame containing measures.

### Examples

    s <- scNMFSet(count=matrix(rpois(n=12,lambda=3),4,3))
    s <- vb_factorize(s,ranks=seq(2,4))
    measure(s)
