Output formats (HTML, PDF, Word) in R Programming

Introduction

We use different output formats to share our results in ways that others can easily read or print. HTML is good for web pages, PDF for fixed layouts, and Word for editable documents.

When you want to create a web page report from your data.

When you need a printable report that looks the same on any device.

When you want to send a report that others can edit in Word.

When sharing results with people who prefer different file types.

When automating report generation in different formats for presentations.

Syntax

R Programming

rmarkdown::render(input = "file.Rmd", output_format = "html_document")
rmarkdown::render(input = "file.Rmd", output_format = "pdf_document")
rmarkdown::render(input = "file.Rmd", output_format = "word_document")

The render function converts your R Markdown file into the chosen format.

You need to have the required software installed for PDF output (like LaTeX).

Examples

This creates an HTML file from the R Markdown file report.Rmd.

R Programming

rmarkdown::render("report.Rmd", output_format = "html_document")

This creates a PDF file from the same R Markdown file.

R Programming

rmarkdown::render("report.Rmd", output_format = "pdf_document")

This creates a Word document from the R Markdown file.

R Programming

rmarkdown::render("report.Rmd", output_format = "word_document")

Sample Program

This program converts the R Markdown file example_report.Rmd into three formats: HTML, PDF, and Word.

Make sure you have LaTeX installed to create the PDF.

R Programming

library(rmarkdown)

# Create HTML output
render(input = "example_report.Rmd", output_format = "html_document")

# Create PDF output
render(input = "example_report.Rmd", output_format = "pdf_document")

# Create Word output
render(input = "example_report.Rmd", output_format = "word_document")

Important Notes

PDF output requires LaTeX software like TinyTeX or MiKTeX installed on your computer.

HTML output is great for sharing on websites or viewing in browsers.

Word output is useful if you want others to edit the report easily.

Summary

Use rmarkdown::render() to create reports in HTML, PDF, or Word formats.

Choose the format based on how you want to share or use your report.

Remember to install extra software for PDF output.
