For example, this document will read args and output_file from the environment created by shiny_prerendered_html()'s invocation.

---
title: "Untitled"
output: html_document
runtime: shiny_prerendered

---

```{r}
args
output_file
```

The result looks like this:

The culprit is this new.env():
https://github.com/rstudio/rmarkdown/blob/6def14c/R/shiny_prerendered.R#L125

Perhaps it should have parent=globalenv()?

* Fix #1162: use parent.frame() of run() instead of new.env() inside rmarkdown_shiny_server() to evaluate code chunks

This should be the correct fix to #619, instead of the PR #624, which introduced new.env().

* use parent.frame() instead of new.env() for shiny_prerendered docs (fixes #1124)

* tweak news

@yihui
Fix #1193: adjust the environment in which R code chunks in Shiny Rmd… 
… are evaluated

The environment should not be simply render_args$envir (which defaults to parent.frame() in render()), because Shiny's input/output/session variables are not available in this environment. We have to create a new environment with the environment of Shiny's server function environment being its parent, and render_args$envir being its grandparent environment.

All previous relevant cases #1162, #619, and #1124 have been tested.

Also closes #1194.
