r-libraries-in-c

R is a language and environment for statistical computing and graphics. It includes an effective data handling and storage facility, a large, coherent, integrated collection of intermediate tools for data analysis. We aim to develop R libraries to deliver good performance, it will support basic form operations and understanding the space time complexity in different platforms.

The objective is to :-

1. Develop R libraries in C
2. Visualization of data points
3. Comparative study of space time complexity on different platforms

How to Build .so file from .c file using gcc on Linux ( Ubuntu ) Terminal

gcc -shared -o sortingLibrary.so -fPIC sortingLibrary.c

Steps to load the .so file on R Console using Terminal :

dyn.load('sortingLibrary.so')

.C("main")

This will execute the library file.

Execution result may vary according to the system configuration.

The screenshots of the execution results attached holds system configuration as :

• Processor : Intel Core i5
• RAM : 8 GB
• System Type : 64 bit Operating System
