title: Adding COUNT in barplot in R
body: <p>I am  a beginner in R. I am having problem in putting the count in my bar plot. </p>
  
  <p>So my data look like this</p>
  
  <pre><code>&gt; head(worker)
    stateur statemb state age tenure    joblost
  1     4.5     167    42  49     21      other
  2    10.5     251    55  26      2 slack_work
  3     7.2     260    21  40     19      other
  4      NA     245    56  51     17 slack_work
  5     6.5     125    58  33      1 slack_work
  6     7.5     188    11  51      3      other
  </code></pre>
  
  <p>I have plot the bar graph by using this code</p>
  
  <pre><code>table=table(worker$joblost)
  barplot(table, main = "Vertical Bar Plot of the Job Lost")
  </code></pre>
  
  <p>But I want to put the frequency for each category of joblost on top of each bar. What can I do?</p>
