Mapframe

A mapframe object is a class of data.frame that contains mapped information, or a data.frame with equivalent properties. The leftmost two columns of every mapframe object must be as follows:

• chr: Chromosome/sequence labels in the order defined for the current reference genome.

• pos: Map positions in increasing order within each chromosome/sequence. The map unit used in a mapframe position column must be indicated by setting its 'map.unit' attribute.

Any number of additional data columns can be included. If present, the row names indicate the locus IDs, which should be unique within the given mapframe.
