title: Vectorise an imported variable in R
body: <p>I have imported a CSV file to R but now I would like to extract a variable into a vector and analyse it separately. Could you please tell me how I could do that? </p>
  
  <p>I know that the <code>summary()</code> function gives a rough idea but I would like to learn more.</p>
  
  <p>I apologise if this is a trivial question but I have watched a number of tutorial videos and have not seen that anywhere.</p>
