title: function in R to determine sample sizes to compare population means
body: <p>Looking to determine sample sizes for both my experimental and control groups (I want only a small portion of my participants in my experimental condition, not a 50/50 split) in order to compare population means. </p>
  
  <p>I'm using the bpower function from the Hmisc R package, specifically bsamsize to compare population proportions, but was wondering if there was an equivalent function for comparing means.</p>
