## Miscellaneous SingleCellExperiment methods

### Description

Miscellaneous methods for the SingleCellExperiment class that do not fit in any other documentation category.

### Available methods

In the following code snippets, `x` and `object` are SingleCellExperiment objects.

`show(object)`:

  Print a message to screen describing the contents of `object`.

`objectVersion(x)`:

  Return the version of the package with which `x` was constructed.

`sizeFactors(object)`:

  Return a numeric vector of size factors of length equal to `ncol(object)`. If no size factors are available in `object`, return `NULL` instead.

`sizeFactors(object) <- value`:

  Replace the size factors with `value`, usually expected to be a numeric vector or vector-like object. Alternatively, `value` can be `NULL` in which case any size factors in `object` are removed.
