title: knit2html put .md in specified path
body: <p>In this following MWE on a Windows 7 machine running R 3.12</p>
  
  <p>I am trying to create an md file from an Rmd.  It creates the md file in my working directory, not int he specified path.  The HTML file is created in the specified path instead.  How can I make the md get created in <code>deleteMe/my.md</code>?</p>
  
  <p><strong>## Create  a minimal Rmd:</strong></p>
  
  <pre><code>dir.create("deleteMe")
  
  cat("\nminimal", file = "deleteMe/my.Rmd")
  </code></pre>
  
  <p><strong>## knit it to md</strong></p>
  
  <pre><code>knitr::knit2html(input = "deleteMe/my.Rmd",  output = "deleteMe/my.md")
  </code></pre>
  
  <p><strong>## If I set the working directory to deleteME it is correct but I'm don't like to use setwd in functions</strong></p>
  
  <pre><code>setwd("deleteMe")
  knitr::knit2html(input = "deleteMe/my.Rmd",  output = "deleteMe/my.md")
  </code></pre>
  
  <p>I realize it's a <code>knit2html</code>, not <code>knit2md</code>, but it creates an md as well.  I'm open to other functions/packages/methods if this is the wrong approach.  I do not want a yaml though as this is for a README.md creation that I don't want the yaml to appear in.</p>
