What is an R file?
An .R file is most commonly an R Script File created for The R Project for Statistical Computing. These files contain plain text source code written in the R programming language. Data scientists and researchers use this language for statistical computing, data analysis, and mathematical modeling.
However, the .R extension has multiple meanings across different systems. It can also be a compiled business application file used by Progress OpenEdge ABL, a Ratfor source code file, a REBOL script, a Rez source code file from Apple, a right audio channel file, or even part of a WinRAR compressed archive.
Identifying the Exact Format
Because an .R file can belong to many different programs, you should not guess its contents. You can use viewer.online/r to analyze .R files to identify the exact format and creator software. Our tool allows you to inspect the file structure, extract readable text, and check whether an online preview is available.
How to open R files?
If your .R file is a standard R Script File, you can open and read the code with any standard text editor like Notepad++ or Visual Studio Code. To actually run the statistical commands, you must install the R environment and an interface like RStudio.
If you need to share the script with someone who does not write code, we recommend using convert.guru to convert the .R file into a .TXT, .PDF, or .HTML document.
Summary
viewer.online/r is useful for identifying, inspecting, and understanding .R files without installing software or dealing with compatibility problems. Whether your file contains statistical code, a compiled business application, or compressed data, our analyzer will help you discover its true format instantly.
