> power.t.test(n=25, delta=0.1, sig.level=1.1, strict=TRUE, type="one.sample")

     One-sample t test power calculation 

              n = 25
          delta = 0.1
             sd = 1
      sig.level = 1.1
          power = 1.088311
    alternative = two.sided

### power can never be over one!  Of course, sig.level should not take value > 1
### either.
### Possible solution: A check in the input to truncate sig.level into [0, 1]??
