Hi IP,

the line
Loading required package: mvtnorm
is a hint that you are using an outdated version of PowerTOST. Since the first five columns are correct, try this:

library(PowerTOST) power.TOST(CV=0.262, n=30) # case 1 # [1] 0.8005133 my result power.TOST(CV=0.262, n=c(15, 15)) # case 2 # [1] 0.8005133 my result

If the first case “works” and you get an error in the second case, try

power2.TOST(CV=0.262, n=c(15, 15))

If you get the correct result this time I suspect that your version is ≤1.2-5. Try

packageVersion("PowerTOST")

My code requires ≥1.2.6 (2015-01-23). power2.TOST() was depreciated in 1.2.6 and removed in 1.2.7 (2015-06-03); the current version is 1.2.8 (2015-07-10).

In my posts I always presume the current version of R and libraries.
