Hello Data Scientists,
Let me continue from my last blog “Why Data Scientists prefer R?” where I shared my personnel choice of embracing R as the preferable tool for statistical analytics. I had articulated top 10 reasons for me to pick it up as listed below (again):
- Open source software.
- Easy to install across platforms.
- Standalone computing and individual servers.
- Extensive library of statistical packages.
- Extra ordinary Data Visualization.
- RStudio is big plus, easy to use IDE.
- Easy to integrate with other packages like Excel, SAS.
- Easy to create scripts and pass on to other stakeholders.
- Trend for R in flying high, it’s in thing in Data Statistical category.
- Higher average salary for R practitioners.
Given that we had decided to move ahead with R as our programming language and the tool for statistical analytics, let me walk you through step by step guide how to install R and R Studio.
Step 1: Smart way to install is to search “Download R” on www.google.com
Step 2: From the google search result, click link having title “R: The R Project for Statistical Computing” this url is the home page for R open source community.
Step 3: Click “download R” on the home page, it will redirect to CRAN site. CRAN is Comprehensive R Archive Network in simple words to distribute the download requests across globe various nodes are setup in each geography, like for India node (server) is setup in IIT Madras for quick response. Each node is hooked up with base server which makes sure all nodes have latest and greatest packages. It is recommended to pick nearest node for optimal download speed.
Step 4: At the nearest CRAN node, click on the “Download R“ for that matches your operating system. Download for R is available for all Operating systems be it Linux, Mac or Windows. On clicking for the right OS link, it will direct you to that OS specific section as shown in the snapshot below. Click “install R for the first time“.
Step 5: Click “Download R 3.4.1 for windows” for windows OS, similarly you will be directed for other set of OS as well.
Step 6: Save executable(setup) R-3.4.1-win.exe, to your local system. Once done click executable follow install wizard step by step.
Once R framework is installed, it is recommended to install R Studio which is the IDE for R. As a .NET developer I personally prefer good UI for development. It is not mandatory to install R Studio but it is an individual preference.
Step 7: To install R Studio search “Download R Studio” on www.google.com.
Step 8: Click “Download RStudio – RStudio”. To install R Studio search “Download R Studio” on www.google.com. It will take you to the RStudio site.
Step 9: Click Download underneath RStudio Desktop (Open Source License) i.e., first DOWNLOAD button. This version is s FREE however there are other versions listed with license fee cost, choose as you need one for your work.
Step 10: Click “DOWNLOAD” Green Button underneath RStudio Desktop (Open Source License) i.e., first DOWNLOAD button.
Step 11: Click appropriate installer for the OS version you want. I clicked “ RStudio 1.0.153 – Windows Vista/7/8/10” for windows 10 for my laptop.
Step 12: Save executable(setup) RStudio-1.0.153.exe, to your local system. Once done click executable follow install wizard step by step.
Once Installed Launch R Studio, it will look like as below.
With this you are all set to go head and start practicing R using RStudio. In my next blog, I will begin with “Basic operations for R”.
Thank you once again for taking time out to read through this article, I hope it was helpful and you will be successfully able to install R framework and R Studio. Kindly share your valuable and kind opinion. Please do not forget to suggest what you would like to understand and hear from me in my future blogs.
