Container for SNP-level annotations used in stratified heritability analysis. Supports binary (0/1) and continuous annotations, classified as baseline (always jointly fitted) or candidate (evaluated via score statistics).
It is a RangedSummarizedExperiment: SNP positions in
rowRanges, the annotation matrix in the annotations
assay, and the per-annotation table in colData. Subsetting works
in both directions – x[i, j] narrows SNPs and annotations
together – and getBaseline / getCandidates
are column subsets rather than reconstructions.
