AllIdentical: Test Multiple Objects for Exact Equality

Description

The function identical() is the safe and reliable way to test two objects for being exactly equal. But it is restricted to the comparison of two objects. AllIdentical() allows the input of multiple objects and returns TRUE in the case that all of them are exactly equal, FALSE in every other case.

Usage

AllIdentical(...)

Arguments

…

any R objects

Details

The function checks the first object against all others, so if the first object is identical to the second and to the third, then also the second and the third are identical. (If A=B and A=C then is B=C)
