Introduction to Indiedown

Create an customized R Markdown template

# install.packages("devtools")
devtools::install_github("cynkra/indiedown")

To create your own customized R Markdown template, start by creating an indiedown template package, called mydown in this example. Navigate to the directory where you want to create the package, then:

indiedown::create_indiedown_package("mydown")

This creates a package skeleton in the new mydown directory in the current working directory. You can build mydown, using “Build and Reload” in the RStudio or via the command line, as follows:

devtools::install("mydown")

With mydown built and installed, our new template is available in RStudio (after a restart):

Customization points

indiedown does not modify the default .tex template of Pandoc. Instead, all modifications are applied on top of it. This should make it compliant with future releases of Pandoc and R Markdown.

There are three possible customization points to customize an indiedown skeleton:

• Set defaults (such as fonts or geometry) in the YAML header at inst/indiedown/default.yaml

• Tweak LaTeX settings at inst/indiedown/preamble.tex

• Apply dynamic adjustments in pre_processor.R (advanced)

See the vignette("customize") for details.

Corporate Design Elements

Indiedown packages use R functions to generate LaTeX code for customization.

For most customizations, it is recommended to turn off the default LaTeX title page and create your own title page via LaTeX commands. The basic repertory are the LaTeX commands \large, \Large, \LARGE, \huge, etc, along with vspace{1ex}, but all LaTeX trickery can be applied. The LaTeX helper functions should be put in the R folder of your package.

The function cd_page_title() creates an example title page that can be adjusted to your needs. Note that the example uses raw strings, which are only available in R >= 4. They make it easy to write LaTeX code directly in R. See details in ?indiedown_glue for methods that work well with R < 4.
