Power of t test for unequal variances?

Mon, Dec 19, 2016 1:47 PM

Is there a function similar to stats::power.t.test that can handle unequal variances from two samples?
I noticed that stats::t.test has an argument for indicating whether or not to treat the two sample variances as equal.? Wondering why stats::power.t.test doesn?t have that option.
Thanks,Mauricio
