pgVirtualLoc-class: Superclass for gene location aware pangenome
Description
This virtual class should be subclassed by all classes that include
chromosomal position of the genes (along with subclassing pgVirtual). The
class itself is an empty shell that only takes care of dispatching and
checking the promises of subclasses are held.
Details
Subclasses of pgVirtualLoc must implement the following methods:
- geneLocation(object)
- Return a data.frame with a row for each gene,
describing the chromosomal position of the gene. The data.frame must contain
the columns 'contig', 'start', 'end' and 'strand'. Contig is
self-explanatory, start and end is the respective start and end positions on
the contig (start must be lower than end) and strand defines the coding
direction as -1 or 1.
