QFeatures-subsetBy: Subset by feature name

In QFeatures: Quantitative features for mass spectrometry data

Description

This function will find the assays and features that match directly (by name) or indirectly (through aggregation) the feature name.

The subsetByFeature function will first identify the assay that contains the feature(s) i and filter the rows matching these feature names exactly. It will then find, in the other assays, the features that produces i through aggregation with the aggregateQFeatures function.

See QFeatures for an example.

y	A character of feature names present in an assay in x.
