vsetdiff: Find all elements in first argument which are not in second...

In vecsets: Like Set Tools in 'Base' Package but Keeps Duplicate Elements

Find all elements in first argument which are not in second argument.

Description

Finds all elements in first argument which are not in the second argument. Unlike the base::setdiff function, if the vectors have repeated elements in common, only the "excess" number of a given element are returned.

Usage

vsetdiff(x, y, multiple = TRUE)

Arguments

x	A vector or an object which can be coerced to a vector
y	A vector or an object which can be coerced to a vector
multiple	Should repeated "multiple" items be returned? Default is TRUE; if set to FALSE, vintersect acts like the base::intersect function.

Value

A vector of all elements in x which are not in y. If multiple=FALSE is set, only unique values are returned.

Examples

x <- c(1:5,3,3,3,2,NA,NA)
y<- c(2:5,4,3,NA)
vsetdiff(x,y)
vsetdiff(x,y,multiple=FALSE)
setdiff(x,y) # same as previous line
vsetdiff(y,x) #note the asymmetry
