Bioc-container specific data set annotation extraction functions

Takes dataset-level annotion as stored by each type. DGEList has no such slot, unfortunately, and thus gets the default. SE has a metadata slot and can provide url and description. eSet just has a character annotation and can provide a description.

ds_annot(x, meta = NULL, validate = FALSE, ...)

Arguments

x	SummarizedExperiment, ExpressionSet or DGEList
meta	a list of description stuff for the dataset, this can act to override what's there, already
validate	single logical, check results
...	additional args (ignored for now)

Details

This is an internal helper function.
