Output formats (HTML, PDF, Word) in R Programming - Mini Project: Build & Apply

Output formats (HTML, PDF, Word)

📖 Scenario: You work as a data analyst and need to share your analysis results with your team. Different team members prefer different formats: some want HTML reports to view in browsers, others want PDF files for printing, and some want Word documents for editing.

🎯 Goal: Learn how to create output files in HTML, PDF, and Word formats using R. You will write code to generate a simple report in each format.

📋 What You'll Learn

Create a simple data frame with sample data

Set up output file names for HTML, PDF, and Word

Use R Markdown to generate reports in each format

Print confirmation messages after each report is created

💡 Why This Matters

🌍 Real World

Creating reports in multiple formats helps share data analysis results with different audiences who prefer different file types.

💼 Career

Data analysts and scientists often need to produce reports in HTML, PDF, and Word formats for presentations, documentation, and collaboration.

1

Create sample data frame

Create a data frame called sales_data with two columns: Product containing "Pen", "Notebook", "Eraser" and Sales containing 150, 200, 100 respectively.

R Programming

# Create the data frame sales_data with Product and Sales columns
# Your code here

Need a hint?

Use data.frame() with named vectors for columns.

2

Set output file names

Create three variables: html_file set to "report.html", pdf_file set to "report.pdf", and word_file set to "report.docx".

R Programming

sales_data <- data.frame(
  Product = c("Pen", "Notebook", "Eraser"),
  Sales = c(150, 200, 100)
)
# Create variables html_file, pdf_file, and word_file with exact file names
# Your code here

Need a hint?

Assign strings to variables using <-.

3

Generate HTML report using R Markdown

Use the rmarkdown::render() function to create an HTML report from a file named "report.Rmd". Set the output file to the variable html_file. Assume report.Rmd exists and uses sales_data.

R Programming

sales_data <- data.frame(
  Product = c("Pen", "Notebook", "Eraser"),
  Sales = c(150, 200, 100)
)

html_file <- "report.html"
pdf_file <- "report.pdf"
word_file <- "report.docx"

# Render the HTML report using rmarkdown::render()
# Your code here

Need a hint?

Use rmarkdown::render() with input, output_file, and output_format arguments.

4

Print confirmation message

Print the message "HTML report created: report.html" exactly using print().

R Programming

sales_data <- data.frame(
  Product = c("Pen", "Notebook", "Eraser"),
  Sales = c(150, 200, 100)
)

html_file <- "report.html"
pdf_file <- "report.pdf"
word_file <- "report.docx"

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

# Print confirmation message
# Your code here

Need a hint?

Use print() with the exact message string.
