Description Usage Arguments Details Value Author(s) See Also Examples

Set operation functions in the base package, union, intersect and setdiff, can only be applied to binary manipulations involving two sets. Following functions, munion, mintersect and msetdiff, extend their basic versions to deal with multiple sets.

1	munion(...)

...

Vectors of items, or a list of them. See examples below.

These functions apply set manipulations (union, intersect, or difference) in a sequential manner: the first two sets are considered first, then the third, the fourth and so on, till all sets have been visited.

A vector of set operation results. Can be an empty vector if no results were returned.

union, intersect and setdiff.

set1 <- c("HSV", "FCB", "BVB", "FCN", "HAN")
set2 <- c("HSV", "FCB", "BVB", "HAN")
set3 <- c("HSV", "BVB", "FSV")

munion(set1, set2, set3)
mintersect(set1, set2, set3)
msetdiff(set1, set2, set3)

## sets can be given in a list as well
munion(list(set1, set2, set3))
mintersect(list(set1, set2, set3))
msetdiff(list(set1, set2, set3))
