This would be a better fit with the on-topic criteria for CV, since it appears the problem is at the very least a lack of understanding of the principles of power analysis rather than primarily a coding difficulty. You might mention that you hoped to use a function by the name of `binom.power` in some non-base package (which you should offer).
