title: having trouble sourcing a file in Rmd
body: <p>I am having trouble sourcing a file into my Rmd file.</p>
  
  <p>I have sourced files before and can not figure out why this one won't work. I have my working directory set to the correct spot. I have a file called projects in that I have my "index.Rmd" file and then I have a folder "scripts" with includes "chart_1.R". </p>
  
  <p>So my work flow would be projects -> scripts. In projects I have index.Rmd and in scripts I have chart_1.R</p>
  
  <pre><code>source("scripts/chart_1.R")
  </code></pre>
  
  <p>I should be able to access the chart_1 file but I am not able to.</p>
  
  <p>It gives me the error "Error in file(file, "rt") : cannot open the connection"</p>
