Admin | R Programming: An Overview | 4409
What is R? R is a programming language that is used for graphics and statistical computing. It is highly extensible, and provides a wide variety of statistical and graphical techniques. One of the reasons for R’s popularity is that it eases the production of well-designed publication-quality plots. Apart from the academia industry, many large companies like Uber, Google, Airbnb, and Facebook use R programming language. It is widely used by data miners and data scientists for analyzing the data. Not just data scientists, but R Programming Training is quite popular among statisticians as well. Where is R used?
  • Statistics
  • Data Science
  • Research Programmes
  • Machine Learning
Most commonly used R packages R packages are a group of R functions, complied code and sample data. They are installed by default during installation.
  • dplyr: By constraining the options, it helps the users think about their data manipulation challenges. It is used for common data manipulation tasks.
  • ggplot2: It is a system for creating graphics.
  • table: This package reduces programming and compute time tremendously during data manipulation operations.
  • Shiny: It eases the process of building interactive web apps straight from R.
  • plyr: It is a set of tools for a common set of problems, like fitting the same model each patient subsets of a data frame.
  • reshape2: This R package makes it easy to transform data between wide and long formats.
