title: Making a table that contains Mean and SD of a Dataset
body: <p>I am using this dataset: <a href="http://www.openintro.org/stat/data/cdc.R" rel="nofollow noreferrer">http://www.openintro.org/stat/data/cdc.R</a>
  to create a table from a subset that only contains the means and standard deviations of male participants. The table should look like this:</p>
  <pre><code>                  Mean                  Standard Deviation
  Age:              44.27                 16.715
  Height:           70.25                 3.009219
  Weight:           189.3                 36.55036
  Desired Weight:   178.6                 26.25121
  </code></pre>
  <p>I created a subset for males and females with this code:</p>
  <pre><code>mdata &lt;- subset(cdc, cdc$gender == (&quot;m&quot;))             
  fdata &lt;- subset(cdc, cdc$gender == (&quot;f&quot;))
  </code></pre>
  <p>How should I create a table that only contains means and SDs of age, height, weight, and desired weight using these subsets?</p>
