An R list with one element each for
BSgenome.Hsapiens.1000genomes.hs37d5,
BSgenome.Hsapiens.UCSC.hg38 and BSgenome.Mmusculus.UCSC.mm10.
Each element is in turn a sub-list keyed by
exome, transcript,
and genome. Each element of the sub list
is keyed by the number of rows in the catalog class (as a string, e.g.
"78", not 78). The keys are:
78 (DBS78Catalog), 96 (SBS96Catalog), 136 (DBS136Catalog),
144 (DBS144Catalog), 192 (SBS192Catalog),
and 1536 (SBS1536Catalog). So, for example to get the exome
abundances for SBS96 catalogs for BSgenome.Hsapiens.UCSC.hg38 exomes
one would reference
all.abundance[["BSgenome.Hsapiens.UCSC.hg38"]][["exome"]][["96"]]
or all.abundance$BSgenome.Hsapiens.UCSC.hg38$exome$"96".
The value of the abundance is an integer vector with the K-mers
as names and each value being the count of that K-mer.
