title: How to manually change the x-axis label in ggplot?
body: <p>I want to change the x-axis labels of my ggplot. Below is my sample code</p>
  
  <pre><code>DF &lt;- data.frame(seq(as.Date("2001-04-01"), to= as.Date("2001-8-31"), by="day"),
                   A = runif(153, 0,10))
  colnames(DF)&lt;- c("Date", "A")
  ggplot(DF, aes(x = Date, y = A))+
    geom_line()+
  scale_x_date(date_labels = "%b", date_breaks = "month", name = "Month")
  </code></pre>
  
  <p>I tried <code>scale_x_discrete(breaks = c(0,31,60,90,120), labels = c("Jan", "Feb","Mar","Apr","May"))</code> with no success. I know my data is from April but would like to change the labels pretending that its from January.</p>
