title: how do you create sections and new lines in knitr
body: <p>I am working on my first knitr document. I've made a lot of progress but, could figure out two things yet.</p>
  
  <p>I am trying to do two things:</p>
  
  <ol>
  <li>Insert section</li>
  <li>insert new lines</li>
  </ol>
  
  <p>I have this code to create section for each application, print heading, charts:</p>
  
  <pre><code>```{r qplot,fig.width=10, fig.height=8, message=FALSE, results = 'asis', echo=FALSE, warning=FALSE, fig.cap='long caption', fig.scap='short'}
  
  library(ggplot2)
  library(knitr)
  cat(paste("Application Name-", App))
  cat("\n"
  print(ggplot(data, aes(Date, cpu))+geom_line()
  cat("\n")
  ```
  </code></pre>
  
  <p>I see that Application Name text is on the same line as the charts. cat("\n") does not seem be working. Also, how would I insert section in pdf so that if I click on a section, it will take to the correct section?</p>
