Progress Software does not provide an official tool or feature to decompile .r files (r-code) back into readable source code. Reversing r-code is not officially supported and may violate license agreements.
The Challenge of Decompilation
If your goal involves recovering source code from compiled or binary formats (not typical for R), or if you're trying to reverse-engineer a process saved in an .RData or similar, share more details, and there might be more specific advice available. decompile progress r file link
If you only need to find hardcoded values, table names, or specific text without fully reverse-engineering the logic, use a hex editor. Open the .r file in a hex editor (like HxD). Search for plain text strings.
If you are managing a large environment and need to ensure your .r files match your source code, you aren't looking for a decompiler—you're looking for CRC Management. Progress Software does not provide an official tool
Unlike languages like C++ or Java, which compile source code into binary machine code, R is an interpreted language. Strictly speaking, R scripts (.R files) do not need to be "decompiled"—they are plain text.
If the file was compiled with the DEBUG-LIST option, the .r file contains a "link" to a debug listing. By running the code through the OpenEdge Debugger, you can sometimes step through the execution and view the source logic as it executes.

Since Progress doesn't offer a native "uncompile" feature, the best lead I’ve found is the Progress R-code Decompiler
