title: What does the estimate column tell us in the summary function?
body: <p>Here is my code</p>
  <pre><code># create a model from the training data comparing the TargetField to the others
  lm.fit &lt;- lm(TargetField ~ .,train) 
  
  # output a summary of the model
  summary(lm.fit)
  </code></pre>
  <p>The output is something like</p>
  <p><a href="https://i.stack.imgur.com/TV0ZX.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/TV0ZX.png" alt="summary output" /></a></p>
  <p>My question is, What does the <code>Estimate</code> column in the output tell us?</p>
  <p>I tried typing</p>
  <pre><code>? summary.lm 
  </code></pre>
  <p>in the console panel of RStudio but I do not see &quot;Estimate&quot; mentioned.</p>
