R Markdown is a file format that allows users to create dynamic documents, reports, and presentations using the R programming language. It combines plain text with embedded R code, enabling users to generate high-quality outputs that include both text and data visualizations. This makes it a popular choice for data analysis and statistical reporting. The documents created with R Markdown can be easily converted into various formats, such as HTML, PDF, and Word. This versatility allows users to share their findings in a professional manner, making it an essential tool for researchers, data scientists, and anyone working with data.
