title: Understanding `scale` in R
body: <p>I'm trying to understand the definition of <code>scale</code> that R provides. I have data (<code>mydata</code>) that I want to make a heat map with, and there is a VERY strong positive skew. I've created a heatmap with a dendrogram for both <code>scale(mydata)</code> and <code>log(my data)</code>, and the dendrograms are different for both. Why? What does it mean to scale my data, versus log transform my data? And which would be more appropriate if I want to look at the dendrogram illustrating the relationship between the columns of my data?</p>
  
  <p>Thank you for any help! I've read the definitions but they are whooping over my head.  </p>
