Hi ElMaestro,

❝ y[i]= sampleN.TOST(CV=CV, targetpower=tpow, theta0=x[i], print=FALSE)[1,7]

A suggestion.

❝ PS: Correct, I am not entirely comfy with the tapply, sapply, apply family of functions.

You are not alone. To complicate things, in PowerTOST many functions are not or only partly vectorized. See the script in this article for a remedy (click on Code to show it).
