Inline R code in R Programming

Introduction

Inline R code lets you run small pieces of R inside text or documents. It helps show results directly with your explanation.

When writing reports that include calculations and results together.

When you want to show a number or result inside a sentence automatically.

When creating dynamic documents that update results if data changes.

When explaining code and showing output side by side.

When making presentations that include live R results.

Syntax

R Programming

`r expression`

Use backticks and start with r followed by the R expression.

This is often used inside R Markdown documents to mix text and code.

Examples

This will show the result 4 inline.

R Programming

`r 2 + 2`

This calculates the average of the numbers and shows 3.

R Programming

`r mean(c(1, 2, 3, 4, 5))`

This joins words and shows Hello world!.

R Programming

`r paste('Hello', 'world!')`

Sample Program

This R Markdown document shows how inline R code works by calculating and displaying results inside text.

This is an example of inline R code:

The sum of 5 and 7 is `r 5 + 7`.

The average of 10, 20, and 30 is `r mean(c(10, 20, 30))`.

The current date is `r Sys.Date()`.

Important Notes

Inline R code only works inside R Markdown or similar tools that support it.

Make sure your R expressions are simple and quick to run for smooth document rendering.

Summary

Inline R code lets you mix R results directly into text.

Use backticks with r to write expressions.

Great for dynamic reports and documents.
