| makeSeqnameIds {GenomicRanges} | R Documentation |
makeSeqnameIds assigns a unique ID to each unique sequence name
in the input vector. The returned IDs span 1:N where N is the number of
unique sequence names in the input vector.
makeSeqnameIds(seqnames, X.is.sexchrom=NA)
seqnames |
A character vector or factor containing sequence names. |
X.is.sexchrom |
A logical indicating whether X refers to the sexual chromosome
or to chromosome with Roman Numeral X. If |
An integer vector of the same length as seqnames.
The values in the vector span 1:N where N is the number of unique
sequence names in the input vector.

sortSeqlevels for sorting the sequence levels
of an object in "natural" order.
