x |
An object containing strand information. |

All the strand methods defined in the GenomicRanges package
use the same set of 3 values (called the "standard strand levels") to
specify the strand of a genomic location: +, -, and *.
* is used when the exact strand of the location is unknown,
or irrelevant, or when the "feature" at that location belongs to
both strands.
unstrand is not a generic function, just a convenience wrapper to
the generic strand setter (strand<-) that simply does:
strand(x) <- "*" x
