hiAnnotator:Functions for annotating GRanges objects
hiAnnotator contains set of functions which allow users to annotate a GRanges object with custom set of annotations. The
basic philosophy of this package is to take two GRanges objects
(query & subject) with common set of seqnames (i.e.
chromosomes) and return associated annotation per seqnames and
rows from the query matching seqnames and rows from the subject
(i.e. genes or cpg islands). The package comes with three types
of annotation functions which calculates if a position from
query is: within a feature, near a feature, or count features
in defined window sizes. Moreover, each function is equipped
with parallel backend to utilize the foreach package. In
addition, the package is equipped with wrapper functions, which
finds appropriate columns needed to make a GRanges object from
a common data frame.
