title: How do I have multiple lines of the same color with GG Plot
body: <p>I am using ggplot to plot production for over time by gas well.</p>
  
  <pre><code>
  GAS_PRODUCTION_CURVE &lt;- RawdataTest %&gt;% ggplot(mapping=aes(x=DaysOn, y=GasProd_MCF, color=WellID)) + 
    geom_line(size=0.5) + theme_bw() + 
    scale_color_manual(values = cols) + scale_y_continuous(label=comma) + 
    coord_cartesian(xlim = c(0, max(RawdataTest$DaysOn)), ylim = c(0,max(RawdataTest$GasProd_MCF))) + 
    theme(legend.position="none") + xlab("Days On") +
    ylab("Gas Rate [MCF]")
  
  </code></pre>
  
  <p>This gets me the plot that I want (note: this is just a subset of the data). However, I want to have the well data graphed, but color by the variable "RSOperator".  In other words, I want all wells with the same RSOperator to be the same color.  That way users can distinguish the difference in well performance between wells.  Is there a way to adjust my code to accomplish this?</p>
