samediff: samediff: Find Elements in Common, and Unique To, Two Lists

In mwrowe/microRutils: Mike Rowe's Miscellaneous R Utility Functions

Description

samediff returns a list with elements of a and b in common, and unique to each, or numbers of unique elements in such a list.

Usage

samediff(a, b, sort = T, na.rm = F, use.arg.names = F, Ns = FALSE)

Arguments

a	a vector or other object that can be treated as a vector OR a two-element list of vectors; if a is a list, all subsequent arguments must be named and b will be ignored. If use.arg.names==TRUE, the names of the list elements will be used to label the output
b	a second vector or other object that can be treated as a vector unless a is a two-element list, in which case b is ignored.
sort	logical; determines whether the elements of A and B will be returned in alphabetical order
na.rm	logical; should missing values be removed from A and B?
use.arg.names	if true, the names of the variables passed in as argumentsa and b to this function will be substituted for the default names "a.only" and "b.only" in the list returned. Default FALSE.
Ns	logical; if TRUE, return a vector of the numbers of item in common and unique to a and b

Value

• A list, with three named character strings:

  • "in.both": intersection of a and b

  • "a.only": (or the name of a, if use.arg.names==T): elements unique to a

  • "b.only": (or the name of b, if use.arg.names==T): elements unique to b

• ...OR a named numeric vector with the numbers of items in common, unique to a and unique to b, with the same names as above
