![]() R has powerful graphics packages that help in data visualization. To export a CSV file: Write.csv(file_name, “c:/file_name.csv”) Looking forward to becoming a Data Scientist? Check out the Data Science Certification Courses and get certified today. To export an Excel file: Write.xls(file_name, "c:/file_name.txt", sep= "\t")ģ. To export a table: Write.table(file_name, “c:/file_name.txt”, sep=“\t”)Ģ. You can also export different files to another location in R.ġ. csv file is imported using the read.csv function. Table: A table can be loaded in R using the read.table function.Ģ. R enables you to import data from different sources.ġ. The list is created using the list() function. Lists: A list contains elements of different types (numbers, strings, vectors, etc.) It can also include a matrix or a function as its elements. Data Frames: A data frame is a table in which each column contains values of one variable, and each row contains one set of values from each column.ĥ. Suppose we create an array of dimensions (two, three, four) then it creates four rectangular matrices, each with two rows and three columns.Ĥ. Arrays: They can store data in more than two dimensions. They also contain elements of the same types.ģ. Matrices: These are R objects in which the elements are arranged in a two-dimensional layout. Vectors: It is the most basic R object, which has atomic values.Ģ. Now, let's discuss the different data structures available in the R programming language.ġ.

It is available in two formats: RStudio Desktop is a regular desktop application. You can also install RStudio, which is an integrated development environment for R. Here, "Download R for Windows" has been selected.įollow the default options to finish the installation. You can select a suitable operating system and click on it to download. R can be easily downloaded and installed from the CRAN website. It also has a collection of all critical updates, R sources, R binaries, R packages, and other documentation. R is not just a programming language it has a worldwide repository system called CRAN (Comprehensive R Archive Network). It can be easily integrated with popular software, like Tableau, and Microsoft SQL Server. It has an extensive library of packages that makes it easy to implement machine learning algorithms. R offers various statistical and graphical techniques.
