{docorator} is an engine for creating production displays from R. Specifically, {docorator} provides the following functionality:

  • Decorate: Surround displays with document-level headers, footers, and page numbers
  • Output: Export decorated displays to a file such as PDF or RTF

The main function, as_docorator() accepts an R object containing the display as input. For best results with sizing, the table should be prepared via {gt}, or packages that interface with {gt} such as {tfrmt}, and the figure should be prepared with {ggplot2}. Alternatively, the path to a PNG can be passed to {docorator}. Specifically, the x should be one of the following:

  • gt table
  • gt_group (list of gt tables)
  • ggplot2 figure
  • list of ggplot figures
  • path to PNG file (i.e. a previously created figure)
  • list of paths to PNG files

The docorator object, which is saved by default, can then be output using one or both of the following render functions which can be piped together: render_pdf() and render_rtf()

Use 

# install from GitHub
devtools::install_github("GSK-Biostatistics/docorator")

# Load package
library(docorator) 

# Create table (or figure)
mytbl <- gt::exibble |> 
  gt::gt()

# Export display   
mytbl |> 
  as_docorator( 
    display_name = "mytbl",
    header = fancyhead(
      fancyrow(left = "My Study", center = NA, right = doc_pagenum()),
      fancyrow(left = "My Population", center = NA, right = NA),
      fancyrow(left = NA, center = "My Table", right = NA)
    ),
    footer = fancyfoot(
      fancyrow(left = "mypath/mytbl.R", center = NA, right = "Data as of 2025-01-01")
    ) 
  ) |> 
  render_pdf() |>
  render_rtf()

Docorator example

Note

{docorator} requires LaTeX libraries for PDF rendering. If using {tinytex}, the “TinyTeX” bundle covers the core dependencies.
