Data analysis and visualizations in R program
R is an open-source programming language and graphical environment for statistical computing. For data analysis, visualisation, and modelling, statisticians, data scientists, and researchers frequently utilise it. R offers a large selection of packages that can be downloaded, installed, and loaded to extend the capability of the R language. Several of these packages offer specific tools for data handling, statistical analysis, and visualisation.
These are some essential R programming concepts:
- Data types: R supports a wide range of data types, including numeric, character, factor, and logical.
- Data structures: R provides several data structures, such as vectors, matrices, arrays, data frames, and lists, that allow you to organize and manipulate your data in different ways.
- Functions: R provides a wide range of built-in functions for statistical analysis, data manipulation, and visualization. You can also create your own custom functions in R.
- Control structures: R provides control structures such as if-else statements, for loops, and while loops that allow you to control the flow of your code.
- Graphics: R provides powerful and flexible tools for creating high-quality graphics, including scatterplots, histograms, bar charts, and more.
