IDE is required to learn R programming. IDE is the platform that allows you to install the programming language. For instance, for the Python programming language, the Juyter notebook will be used as an IDE. Eclipse IDE will be used for Java development. R studio is an IDE that is used for R programming. It helps you to manage all your programming efforts easily.
R Markdown is used to execute the R code and allows you to save the results in various formats. There are different functionalities that are offered by R Markdown such as it helps you to automatically create HTML files to let you open the solution in the browser, and create a pdf file. There is no need for you to copy and paste the code and get the answers from the console. You can easily create a Word document.
R Notebook is similar to that of R Markdown. This enables you to create appealing reports in R without having to copy the R code and move the results to Word and various other programs. Using R Notebook, you can create an HTML file, meaning that the code is executed with the help of a knitting process. R Notebook previews the output that you get by executing the code in RStudio.
Shiny is an R package that makes it easier for you to create web applications using the R programming language. You can also embed applications on the web pages embed them in R Markdown docs or use them to develop dashboards. The Shiny apps can be used for JavaScript actions, HTML widgets, and CSS themes.
Few of the libraries in R include:
tidyverse (general R library including some of the libraries below): Tidyverse is the most critical R package of data science. There are various other packages that are available under Tidyverse that help you to interact with the data with ease. There are many things that you do with the data like visualizing, transforming, and subsetting. It offers all utilities that are required to clean the data.
Ggplot2: Ggplot2 is the widely used opensource visualization package that is a part of the statistical programming language R. The package is a plotting package that lets you create complicated plots using the data that is in the data frame. There is a programmatic interface to specify the type of variables in the plot, how to display them, and various visual properties.
Dplyr: It is the critical package of Tidyverse in R programming language. It contains a lot of functions that are used to manipulate data frames in an interactive way. The majority of data analysts make use of this library to transform the datasets that are available currently into the format that is suitable for you to carry out data analysis and visualization.
Tidyr: It is an R package that has R functions, compiled code, and sample data. It is stored in a directory called the library in the R environment. When installing the R package, by default this package is installed. The purpose of this package is to make the process of creating Tidy data simple.
Stringr: The Stringr package would offer a lot of functions that work with strings. The package will offer you wrappers and simplify the manipulation of using character strings in R language.
Plotly (interactive graphs): It is the R graphing library that would allow you to make highly interactive graphs. These allow you to make scatter plots, area charts, bar charts, histograms, subplots, 3D charts, and so on.
stargazer (beautiful regression tables): It is an R package that allows you to create Latex code, HTML code, and ASCII text to create a properly formatted regression table.
R Markdown: It is a file format that allows you to make dynamic documents using R. The R Markdown is written in the Markdown language and has huge chunks of embedded R code.
Shiny app: This might be extremely challenging for R newbies! The shiny app allows you to develop highly interactive web apps. The best thing about this app is that it lets you extend R code to the web.
