prereg provides R Markdown templates that facilitates authoring preregistrations of scientific studies in PDF format.

If you experience any problems or have suggestions for improvements, please open an issue.

Setup

Software requirements

prereg depends on additional software, namely,

  1. R 2.11.1 or later and
  2. pandoc 1.19 or later
  3. TeX 2013 or later.

If you work with RStudio (1.1.453 or later) pandoc should already be installed, otherwise refer to the installation instructions for your operating system.

Setting up a TeX distribution

prereg can be used with common TeX distributions, such as MikTeX on Windows, MacTeX on Mac, or TeX Live on Linux.

If you mainly use TeX to render R Markdown documents, we strongly recommend using the TinyTex distribution. It is lightweight and automatically installs missing LaTeX packages. TinyTex can be installed from within R as follows.

if(!"tinytex" %in% rownames(installed.packages())) install.packages("tinytex")

tinytex::install_tinytex()

Install prereg

You can install the stable version of prereg from CRAN

install.packages("prereg")

or the development version from this GitHub repository (you may have to install the remotes package first).

if(!"remotes" %in% rownames(installed.packages())) install.packages("remotes")
remotes::install_github("crsh/prereg")

Create a preregistration document

Once you have installed the prereg you can select the templates when creating a new R Markdown file through the RStudio menus.

Example

prereg produces a clean form-like document.

The template file contains comments that provide further details on how to fill in the form but are invisible in the final PDF document.

Using prereg without RStudio

If you want to use prereg without RStudio you can use the rmarkdown::render function to create preregistration documents:

# Create new COS preregistration challenge R Markdown file
rmarkdown::draft(
  "my_preregistration.Rmd"
  , "cos_prereg"
  , package = "prereg"
  , create_dir = FALSE
  , edit = FALSE
)

# Render document
rmarkdown::render("my_preregistration.Rmd")

Uploading your preregistration

After knitting your preregistration to a PDF file using this package, you may upload this protocol to a trustworthy repository to complete your preregistration. Possible repositories for this are:

Package dependencies
