get_metadata(x)

## S4 method for signature 'Slinky'
get_metadata(x)

Arguments

x

a Slinky object

Details

As it turns out 'metadata' was a poor choice for the accessor function because it can be masked if the user loads the 'SummarizedExperiment' package after slinky. So this provides an alternative. Eventually 'slinky::metadata' should be deprecated.

Value

The accessor function returns a data.frame containing the metadata.
