Convert BSseq object to edgeR methylation matrix

Usage

bsseq_to_edger(bsseq, regions = NULL)

Arguments

bsseq: the BSseq object.
regions: the regions to calculate log-methylation ratios over. If left NULL, ratios will be calculated per site.

Value

a matrix compatible with the edgeR differential methylation pipeline

Examples

methy <- system.file("methy_subset.tsv.bgz", package = "NanoMethViz", mustWork = FALSE)
bsseq <- methy_to_bsseq(methy)
