This Repos include all the relevant material for the summer bootcamp for TechniBits

Course Objectives

Pre-course preparations

• Installing the latest R version or ≥ 3.5 (https://cloud.r-project.org)
• Intalling the latest RStudio Desktop or ≥1.1 (https://www.rstudio.com/products/rstudio/download/)
• Installing latest Git or ≥ 2.7
  • Also install Git Bash for windows

R packages to isntall

During this course we will be using few packages that do not come with the base R. Therefore, I have put a chunk of code in the requirements.txt that will install all the necessary packages for you. All you have to do is open the R-base and copy and paste the content of the file.

Note: the file has a long list and installing all these packages might take sometime. Be patient.
