get.gc.content: Return a named vector of GC-content for each genomic
region
Description
Returns a named numeric vector (names are the
genomic region names, e.g. genes) given a data
frame which can be converted to a GRanges object
(e.g. it has at least chromosome, start, end
fields). This function works best when the input
annotation data frame has been retrieved using one
of the SQL queries generated from
get.ucsc.query, used in
get.ucsc.annotation.
Usage
get.gc.content(ann, org)
Arguments
ann
a data frame which can be converted to a
GRanges object, that means it has at least the
chromosome, start, end fields. Preferably, the output
of link{get.ucsc.annotation}.
