mutateeach.RdInternally create or transform metadata of a GenomicRangesList
mutateeach(x, ...)GRangesList object
Name-value pairs of expressions. The name of each argument will be the name of a new metadata column, and the value will be its corresponding value.
Transformed GRangesList object
# Load dataset
data(query_exons)
# Create chr:start-end id for each entry
mutateeach(query_exons, id = paste0(seqnames, ":", start, "-", end))
