Rmd file is rendered, the knit() function of the package knitr ( Xie 2021b) is used to execute the R code chunksĪnd to generate a markdown file (with extension. Or a document with PDF format by setting output_format=pdf_document. The render() function has an argument called output_format where we can select the format we want for the final document.įor example, we can obtain a document with HTML format if we set output_format=html_document, Rmd file, we can use the ‘Knit’ button in the RStudio IDE or use the render() function of the rmarkdown package. R code chunks with the code that needs to be executed.YAML header specifying several document options such as the output format,.Rmd extension and intermingles R code with text to create a final output in HTML, PDF or other formats.Īn R Markdown file has three basic components, namely: We can install the rmarkdown package by typing install.packages("rmarkdown").Īn R Markdown file has.
