### Examples

    gr = GRanges(seqnames = c("chr5", "chr5"),
    	ranges = IRanges(start = c(98, 98),
    	                 end = c(104, 104)))
    target = GRanges(seqnames = "chr5",
    	ranges = IRanges(start = 100,
    		             end = 100))
    mat1 = normalizeToMatrix(gr, target, extend = 6, w = 1)
    # attributes removed and you cannot use it for EnrichedHeatmap()
    mat2 = mat1[]
    # copy attributes to mat2 and now mat3 can be used for EnrichedHeatmap()
    mat3 = copyAttr(mat1, mat2)
