"crossable"Reference classes extending this virtual class must have a slice method, as a generic cross method based on it is provided.
Its only purpose is currently to add the cross method to "'>track.table", as "'>sliceable" does not guarantee that slice returns a data.frame as crossable needs one.
Class '>sliceable, directly.
Class '>drawable, by class '>sliceable, distance 2.
All reference classes extend and inherit methods from '>envRefClass.
The following fields are inherited (from the corresponding class):
cross(annotation, colname = , type = , fuzziness = , maxElements = , location = , precision = , quiet = ):Add a new column computed from overlaps with an other crossable object. - annotation : other crossable object to compute overlap with. - colname : single character value, the name of the new column to add to .self. If NULL or NA, the result will be returned rather than added to .self. - type : single character value, either : 'cover', to compute coverage of 'annotation' elements for each .self element 'count', to count 'annotation' elements overlapping each .self element 'cytoband', to get cytogenetic coordinates from a cytoband annotation track an 'annotation' column name, to list 'annotation' elements overlapping each .self element - fuzziness : single integer value, to be added on each side of .self elements when computing overlaps. - maxElements : single integer value, when more overlaps are found, lists are replaced by counts. Can be NA to disable this behavior. - location : character vector, the 'chrom' / 'start' / 'end' .self columns to use for annotation. - precision : single integer value from 1 to 4, amount of digits to consider in banding (type='cytoband'). - quiet : single logical value, wether to throw progression messages or not.
