title: Scatter plot with column names on x-axis with classes
body: <p>I want to make a scatter plot where the x-axis is discrete (day of the week) and the y-axis is continuous (values) and a class indicator which gives a color to each data point.</p>
  
  <p>similar to this: <a href="https://stackoverflow.com/questions/51214739/plotting-column-names-as-x-axis-in-r">Plotting column names as x-axis in R</a></p>
  
  <p>but I don't want to use all of the columns in the data and the colors were based on the observation number which I don't want.</p>
  
  <p>example data:</p>
  
  <pre><code>DAT = data.frame(
    person = c(1:5),
    Mon = c(100, 98, 95, 99, 93),
    Tues = c(95, 88, 90, 91, 87),
    Wed = c(85, 80, 86, 81, 80),
    Thurs = c(84, 80, 77, 75, 74),
    Fri = c(66, 50, 20, 0, 72),
    Score = c("Y","Y","N","N","N")
  )
  
  ggplot(DAT, aes(x = c(Mon, Tues, Wed, Thurs, Fri), y = values, color = Score)) + geom_point()
  </code></pre>
  
  <p>my attempt/pesuedo ggplot code which does not work but hopefully gives an idea of what I'm trying to accomplish. </p>
  
  <p>I tried to make Mon-Fri as numbers (1,2,3,4,5) so that would be my x coordinates and the values would be the y-coordinates but that would mean 5 times the number of rows..</p>
  
  <p>Any ideas?</p>
