I want to write some tutorials on Perl 6. For this I believe Rmarkdown would be of great help. 

So I am trying to execute `Perl 6` code within Rmarkdown document.

My Perl 6 executable is in `C:\rakudo\bin`.
So my `.Rmd` file with example code to accomplish this is as follow:

```
---
title: "Example"
output: html_document
---

```{r, engine='perl6', engine.path='C:\\rakudo\\bin'}
my $s= "knitr is really good";
say $s;
```

```

However knitting the above document in Rstudio shows the following without Perl 6 output.

Any help where I am missing?
