Description Usage Arguments Details Value

If the 'DGEList$genes' entry is undefined, the feature data is added as the genes entry; otherwise the new columns are appended to the RHS of the existing genes entry.

1	append_feature_annotations(dge, annotations, feature_id = "feature_id")

`dge`	A DGEList
`annotations`	A data-frame to either use as the 'genes' entry or to append to the 'genes' entry of the DGEList. Will match its 'feature_id' column against the feature ordering in the DGEList.
`feature_id`	Which column of 'annotations' contains the IDs for the features. The contents of this column will be matched against a column of 'dge$genes' - this is preferentially a column of the same name but, if that colname is absent from 'dge$genes', then the rownames of the DGEList will be used.

Ensures that the feature-id / gene-id matches up between the provided data-frame and the existing 'DGEList'

The column named by 'feature_id' must be present in the 'annotations' data frame. If that column is present in the $genes entry of 'dge', matching will be done on that column, otherwise, matching will be done on the rownames of the DGEList.
