Create an article showing off features

[jennybc]

I removed the content below from the vignette, in the name of having no executed code in the vignette. Would like to add it back in an article.

Advanced features

Embedded prose

Sometimes you want to mingle rendered code and prose. Put the embedded prose in as roxygen comments, i.e. comment lines that start with #'. This reprex code:

tmpfile <- tempfile()
demo_code <- c(
  "## a regular comment",
  "x <- 1:100",
  "#' Here is some embedded prose, as a roxygen comment.",
  "mean(x)"
)
md_content <- reprex(
  input = demo_code,
  outfile = tmpfile,
  show = FALSE,
  advertise = FALSE
)
tmpfile <- paste0(tmpfile, "_reprex.md")

cat(demo_code, sep = "\n")

renders to this this result:

leftovers <- list.files(pattern = "README-tmp", ignore.case = TRUE)
if (length(leftovers)) file.remove(leftovers)

This is about creating a pkgdown article (see usethis::use_article() for more) that shows use of reprex beyond the very basics.

The content above was removed in a draconian 2018 effort to remove/disable all sorts of code from running on CRAN.

An article remains safely off of CRAN and can present actual usage of reprex in a natural way, i.e. showing usage with the clipboard.

The examples of reprex() are also a great source of ideas.

Also this talk: https://speakerdeck.com/jennybc/reprex-reproducible-examples-with-r.
All the code snippets are already here: https://github.com/tidyverse/reprex/tree/master/slides/2018-09_reprex-rstudio-webinar

The goal would be an article with a well-named heading for each example, so they are easy to link to from elsewhere.
