What is the .R File Extension?

.R File Extension Description:

The FORTRAN preprocessor is used to run applications on multiple platforms. It will make sure that the following processes are treated in a correct and uniform manner:

* I/O (input/output) file

* conditional compilation

* interlanguage calling sequence

The FORTRAN preprocessor can be divided into two commands, first the syntax checking mode and the full preprocessing mode. The syntax checking mode is used to check only the syntax of the SQL (Structured Query Language) command enclosed in the source code file. The full preprocessing mode is used to check both the enclosed SQL command and then make compliable output that can be managed by the FORTRAN compiler. In 1974, FORTRAN implemented Ratfor as a preprocessor for its Fortran 66 program.

Ratfor (Rational Fortran) is a programming language designed by Brian Kernighan and Bell Telephone Laboratories. It allows the usage of C-like flow expressions (pertaining to the programming language C) and an instructive language for mathematical algorithms. Ratfor programs are easy to write, read, debug, modify and maintain. Source code of Ratfor files end in file extension R. Source code files with the .r file extension are used to create processes, which can be transformed into functioning applications. Software development applications can process source code files with the R file extension. Source code files with the R file extension contain processes needed by software.

Other programs also use the file extension R. Other uses of the R file extension are:

1. The R programming language uses the file extension R as its script file. Script files are used to store any sequence of octave commands.

2. Pegasus Mail Resource also uses the file extension R to store information and source code.

3. REBOL script files use the file extension R. REBOL (Relative Expression Based Object Language) is a symbolic programming language specifically designed for network communications and computing. It supports functional, structured and prototype-based programming.

4. Files with the R file extension are used by REBOL Scriptor data. These files are used to storage, compute and exchange data.
