pwrEWAS
    pwrEWAS is a computationally efficient tool to estimate power in EWAS as a function of sample and effect size 
       for two-group comparisons of DNAm (e.g., case vs control, exposed vs non-exposed, etc.). Detailed description 
       of in-/outputs, instructions and an example, as well as interpretations of the example results are provided in 
       the following vignette:
