I encourage you to edit your question and clarify the purpose of your study (for example, you mentioned measurement, which made me think of comparing means but the provided R code is for proportions). | |

You can say that if the population (true) effect is of a certain magnitude, you have an X percent chance of getting a statistically significant result (that's power), with a sample size of Y. Power of 0.5 is low. | |
