title: Reading one sheet from excel in rstudio
body: <p>I have an excel file with two sheets, A &amp; B.
  I need to upload and use the data in Rstudio from <strong>sheet B ONLY.</strong>
  How can I do that?</p>
  <p>I imported the file to the rstudio and I wrote this :
  <code>dat &lt;- read_excel (&quot;multi_anova.xlsx&quot;)</code></p>
  <p>but when I try to use the data, such as <code>(dat$id)</code> , it gives me all the excels's file id's, not only the B sheet.</p>
  <p>How can I get the B sheet's ids ?</p>
