R Programming refers to a statistical programming language that is used for building probabilistic models, performing data science, and building machine learning algorithms. Professionals having advanced knowledge of R can become R Programmers. R Programmers have a task that involves data analyses and data visualizations using the R package as well as assisting in designing and developing technical architecture. These programmers also coordinate with end-users for designing and implementing analytics solutions as per the project. And, they also create scripts for having proper data access and report functions with R programming languages. Further, in their daily task they also formulate procedures for integrating R programming plans with data sources and delivery systems. And, also provide technical assistance for the development and execution of test plans.
