Overview

r2rtf provides multiple ways to convert RTF format to other formats including PDF, DOCX, and HTML:

User-facing functions: write_docx() and write_html() - Exported functions for converting RTF encoding to DOCX or HTML
Internal function: r2rtf:::rtf_convert_format() - Lower-level function for batch conversion of RTF files

All conversion features require LibreOffice >= 7.1 and currently support Unix/Linux/macOS systems only.

Using write_docx() and write_html()

The write_docx() and write_html() functions provide a simple interface to convert RTF encoding directly to DOCX or HTML formats.

Write DOCX

# Create RTF encoding
rtf <- head(iris) |>
  rtf_body() |>
  rtf_encode()

# Convert to DOCX
write_docx(rtf, "output/table.docx")

Write HTML

# Create RTF encoding
rtf <- head(cars) |>
  rtf_body() |>
  rtf_encode()

# Convert to HTML
write_html(rtf, "output/table.html")

Using rtf_convert_format() (Advanced)

The internal r2rtf:::rtf_convert_format() function provides more control for batch processing of existing RTF files.

By default, r2rtf:::rtf_convert_format converts RTF files to PDF format. The PDF file will be saved in the same folder with same file name by default.

In the example below, ae_example.pdf will be created in the same folder.

r2rtf:::rtf_convert_format(input = "rtf/ae_example.rtf")

Multiple files can be provided as input.

r2rtf:::rtf_convert_format(input = list.files("rtf", pattern = "*.rtf"))

The format argument allows you to specify output format as pdf, docx, or html.

r2rtf:::rtf_convert_format(input = "rtf/ae_example.rtf", format = "html")
