[R] eps parameer in equiv.test

[Sorkin, John]

I am trying to understand the meaning of the eps parameter of the equiv.test parameter of the equiv.test function (package equivUMP)

The help file for equiv.test states that the parameter eps is "a single strictly positive number giving the equivalence limits"
What is the scale of measurement of eps? It does not appear to be the same scale as the scale used for the two vectors that are passed to, and which are tested. Is the eps' scale of measurement the pooled SD of the two vectors, is it the SD of the difference, is it the pooled SE of the difference, is it the SE of the difference? Perhaps it is something entirely different.
Thank you,
John
