Supports concordances in 'R Markdown' 
  documents.  This currently allows the original source
  location in the '.Rmd' file of errors detected by 'HTML tidy'
  to be found more easily, and potentially allows forward
  and reverse search in 'HTML' and 'LaTeX' documents
  produced from 'R Markdown'.  The 'LaTeX' support
  has been included in the most recent development 
  version of the 'patchDVI' package.

A collection of 'Lua' filters that extend the functionality
  of R Markdown templates (e.g., count words or post-process citations).

HTML formats and templates for 'rmarkdown' documents, with some extra
    features such as automatic table of contents, lightboxed figures, dynamic
    crosstab helper.

A series of functions to aid in repeated tasks for Rmd documents. All details are to my personal preference, though I am happy to add flexibility if there are use cases I am missing. I will continue updating with new functions as I add utility functions for myself.

A system for describing and manipulating the many models that are
    generated in causal inference and data analysis projects, as based on the
		causal theory and criteria of Austin Bradford Hill (1965) 
		<doi:10.1177/003591576505800503>. This system includes the addition of 
		formal attributes that modify base `R` objects, including terms and 
		formulas, with a focus on variable roles in the "do-calculus" of modeling,
		as described in Pearl (2010) <doi:10.2202/1557-4679.1203>. For example, the 
		definition of exposure, outcome, and interaction are  implicit in the roles 
		variables take in a formula. These premises allow for a more fluent modeling
		approach focusing on variable relationships, and assessing effect 
		modification, as described by VanderWeele and Robins (2007) 
		<doi:10.1097/EDE.0b013e318127181b>. The essential goal is to help 
		contextualize formulas and models in causality-oriented workflows.

Use 'rmarkdown' partials, also know as child documents in
		'knitr', so you can make components for HTML, PDF, and Word documents. 
		The package provides various helper functions to make certain functions easier. 
		You may want to use this package, if you want to flexibly summarise objects 
		using a combination of figures, tables, text, and HTML widgets. 
		Unlike HTML widgets, the output is Markdown and can hence be turn into other
		output formats than HTML.
