BiocGenerics (version 0.18.0)

sets: Set operations

Description

Performs set union, intersection and (asymmetric!) difference on two vector-like objects.

NOTE: This man page is for the union, intersect and setdiff S4 generic functions defined in the BiocGenerics package. See ?base::union for the default methods (defined in the base package). Bioconductor packages can define specific methods for objects (typically vector-like) not supported by the default methods.

Usage

union(x, y, ...)
intersect(x, y, ...)
setdiff(x, y, ...)

Arguments

x, y

Vector-like objects (typically of the same class, but not necessarily).

...

Additional arguments, for use in specific methods.

Value

See ?base::union for the value returned by the default methods.Specific methods defined in Bioconductor packages will typically return an object of the same class as the input objects.

Examples

union

selectMethod("union", c("ANY", "ANY"))  # the default method

intersect
showMethods("intersect")
selectMethod("intersect", c("ANY", "ANY"))  # the default method

setdiff
showMethods("setdiff")
selectMethod("setdiff", c("ANY", "ANY"))  # the default method
