Fundamentals of R
The course is part of this learning path
This module introduces you to some of the basics of how to interpret data with R.
The objectives of this module are to provide you with an understanding of:
- How to use calculator operations in R
- How to store results with labels
- The difference between print and cat in R
- How libraries can be installed in R
Aimed at all who wish to learn the R programming language.
No prior knowledge of R is assumed.
Delegates should already be familiar with basic programming concepts such as variables, scope, and functions.
Experience of another scripting language such as Python or Perl would be an advantage.
Having an understanding of mathematical concepts will be beneficial.

- [Instructor] Before we understand how to install a package, let us start by defining what is a package. A package is a collection of functions. Possibly including data sets that might be useful That are developed by the R community. Let us remember that the philosophy of R is that it is open sourced and community driven. So where are the packages located? In repositories online. Usually CRAN. And how do we install packages? What's surprising or unusual is that we actually would install a package as part of the console. The main benefit is that we never really have to leave the programming language. We never have to leave the console. So for example, taking a random package and wanting to install it. I can install packages such as, viridisLite utilising this aptly named install.packages function. I can install it and on the screen it will tell me that it's going to the internet, it's going to grab the package, we can have a look and see where this package lives and see that it is going to pick up the package that I would like to install from the CRAN repository. It's downloading that zip file and then successfully unpacking it and then installing it. And if I would like to load this package in, I'd have to run and utilise the library command. Lib, and I'd have to spell it correctly And then by pressing enter and clicking on the Packages tab I can search for this package viridisLite and I can see that it has been installed and it has been loaded.
