The benefit of using a programming language such as R is that we can automate repetitive tasks. This course covers the fundamental techniques such as functions, for loops and conditional expressions. By the end of this course, you will understand what these techniques are and when to use them. This is a one-day intensive course on R.

Course Outline

• Conditionals: using if and else statements in R .

• Functions: what a function is, how are they used, and how can we construct our own functions.

• Looping in R: an introduction to the concept of looping in R. In particular for and while loops.

• The apply functions: applytapply and other members of the apply family.

• Help: The help system in R can at first glance appear daunting, however, after the initial shock, R's documentation is second to none.

• Project structure: Practical tips on how to structure a project.

Learning Outcomes

By the end of the day participants will...

• have a thorough understanding of if and else statements, functions, for loops and the apply family .

• understand how the aforementioned techniques can be applied to their own data .

• understand how these techniques will improve efficiency and results.
