use_epoxy_knitr_engines {epoxy}

Use the epoxy knitr engines

Description

Sets epoxy's knitr engines for use by knitr in R Markdown and other document formats powered by knitr. These engines are also set up when loading epoxy with library(), so in general you will not need to call this function explicitly.

epoxy provides four knitr engines:

• epoxy uses default glue syntax, e.g. {var} for markdown outputs

• epoxy_html uses double brace syntax, e.g. {{var}} for HTML outputs

• epoxy_latex uses double angle brackets syntax, e.g. ⁠<<var>>⁠ for LaTeX outputs

• whisker uses the whisker package which provides an R-based implementation of the mustache templating language.

For historical reasons, aliases for the HTML and LaTeX engines are also created: glue_html and glue_latex. You may opt into a third alias — glue for the epoxy engine — by calling use_epoxy_glue_engine(), but note that this will most likely overwrite the glue engine provided by the glue package.

Usage

use_epoxy_knitr_engines(
  use_glue_engine = "glue" %in% include,
  include = c("md", "html", "latex", "mustache")
)

use_epoxy_glue_engine()

Arguments

use_glue_engine

If TRUE (default FALSE), uses epoxy's glue engine, most likely overwriting the glue engine provided by glue.

include

The epoxy knitr engines to include. Defaults to all engines except for the glue engine (which is just an alias for the epoxy engine).

Value

Silently sets epoxy's knitr engines and invisible returns knitr::knit_engines as they were prior to the function call.

Functions

• use_epoxy_glue_engine(): Use epoxy's epoxy engine as the glue engine.
