| Hits-setops {S4Vectors} | R Documentation |
Perform set operations on Hits objects.
union(x, y), intersect(x, y), setdiff(x, y), and
setequal(x, y) work on Hits objects x and y
only if the objects are compatible Hits objects, that is, if they
have the same subject and query lengths. These operations return respectively
the union, intersection, (asymmetric!) difference, and equality of the
sets of hits in x and y.
union returns a Hits object obtained by appending to x
the hits in y that are not already in x.
intersect returns a Hits object obtained by keeping only
the hits in x that are also in y.
setdiff returns a Hits object obtained by dropping from
x the hits that are in y.
setequal returns TRUE if x and y contain the
same sets of hits and FALSE otherwise.
union, intersect, and setdiff propagate the names and
metadata columns of their first argument (x).
