title: Plot mean, standard deviation, standard error of the mean, and confidence interval
body: <p>I'm using R to plot statistical graphs. I can plot simple graphs. However, I not have idea how to plot complex data.</p>
  
  <p>Someone could help me put together a chart with all this information? Excluding N (count).</p>
  
  <p>My dataset</p>
  
  <pre><code>$ df &lt;- read.csv("database.csv", header=TRUE, sep=",")
  $ df
  
  # df is 'data frame'
  # Gives count (N), mean, standard deviation (sd), standard error of the mean (se), 
  # and confidence interval (ci)
  
                     method   N       mean          sd           se          ci

  <p>I need a simple chart that contains all information of the dataset.</p>
  
  <p>Note: Count (N) and standard error of the mean (se) is not necessary.</p>
  
  <p>For example, how can I create a bar graph and add confidence interval?</p>
