title: Plotting values range against a moving mean for each interval RStudio
body: <p>I'm trying to plot the mean fat percentage for each age group in RStudio. Specifically, I want to barplot the age range (18-24 &amp; 24-30 &amp; 30+) against the mean fat percentage (y-axis) for each of the age groups mentioned. Not sure how to approach it since I'm new to RStudio. I've linked the data for reference: <a href="https://www2.stetson.edu/~jrasp/data/BodyFat.xls" rel="nofollow noreferrer">https://www2.stetson.edu/~jrasp/data/BodyFat.xls</a></p>
  
  <p>Appreciate it.</p>
