It's an alternative implementation of the S programming language, which was widely used in the 1980s for statistical computing. R is a free and open-source scripting language developed by Ross Ihaka and Robert Gentleman in 1993. R, Python, and Julia are popular programming languagues in data analytics and data science. Powerful programming languagues are necessary to perform such tasks. Mathematical or statistical analysis cannot use them either. Business Intelligence applications can't perform such transformations. However, most of the time, data comes in unstructured format and needs preprocessing and transformation.

Data science applies mathematical analysis, statistical techniques, and machine learning algorithms to extract insight from data.īusiness Intelligence (BI) applications like Power BI and Tableau help with analyzing and visualizing data. Data analytics studies how we collect, process, and interpret data.

Transactional data from invoices, payment orders, payment methods, discountsīusinesses and organizations can gain a competitive advantage by analyzing large amount of data ( "big data") to reveal patterns and gain insights.

Machine data from medical devices, satellites, web logs.

Social data from Facebook posts, tweets, google trends.

The primary sources of these data are the following: The amount of data generated daily is expected to reach 463 exabytes by 2025. You’ll need to adjust the path to reflect the location where the Excel file is stored on your computer (don’t forget to use double backslash within the path name to avoid any errors).At the beginning of 2020, the amount of data in the world was estimated at 44 zettabytes. Read_excel("C:\\Users\\Ron\\Desktop\\Products.xlsx") So this is the code to import the Excel file: library("readxl")

The data that is stored in the Excel file is as follows: productįor demonstration purposes, assume that the file is stored under the following path: Let’s say that you want to import an Excel file into R (where the Excel file name is ‘Products’). To start using the package installed, you’ll need to load it in the R Editor.įor instance, to load the readxl package, you’ll have to use: library("readxl") Step 4: Start using the package installed You may choose a mirror which is closer to your geographic location. Step 3: Select a Mirror for the installationįor the final step, select a Mirror for the installation. Once you are done typing the command, press ENTER to proceed with the installation. Now you’ll need to use the following template to install your package: install.packages("package_name")įor example, you may type the following command in the R Console in order to install the readxl package: install.packages("readxl") Step 2: Type the command to install the package
