r2rtf

Overview

r2rtf is an R package to create production-ready tables and figures in RTF format. The package is designed with these principles:

• Provide simple “verb” functions that correspond to each component of a table, to help you translate data frame(s) to a table in RTF file.
• Functions are chainable with pipes (%>%).
• Only focus on table format.
  • Data manipulation and analysis should be handled by other R packages, for example, tidyverse.
• Minimize package dependency.

The R for clinical study reports and submission book provides tutorials by using real world examples.

Installation

You can install the package via CRAN:

install.packages("r2rtf")

Or, install from GitHub:

remotes::install_github("Merck/r2rtf")
