Pass List argument to rmarkdown file (.Rmd)

I am generating an HTML report using rmarkdown. I want to pass the list of the tables through render method but it's throwing me an error:

Error in UseMethod("as.html") : 
no applicable method for 'as.html' applied to an object of class "character"

Code Snippet:

---
params: 
  tables: !r
---
```{r results='asis', echo=FALSE}
for(i in as.list(params$tables)){
  cat("######", as.html(i), "\n")
}

```

Please suggest a way to resolve.

Thank you for the help!

Provide a default for tables, e.g

tables: !r "whatever"

I could not find the requirement in the docs, but it looks like an empty string such as "" does not work.

Add a reference to htmltools

library(htmltools)

There is no function as.html, only HTML in htmltools or shiny:

HTML(i)
