Course start date: Wednesday 26 April 2023 to Thursday 27 April 2023

Duration: 2 day online course

Course Module: Non-accredited

Level: CPD, Advanced / Professional

On this two-day course, you will gain a comprehensive practical introduction to data wrangling using R. In particular, we focus on tools provided by R's `tidyverse`, including `dplyr`, `tidyr`, `purrr`, etc.

Data wrangling is the art of taking raw and messy data and formating and cleaning it so that data analysis and visualization etc may be performed on it.

Done poorly, it can be a time consuming, labourious, and error-prone.

Fortunately, the tools provided by R's `tidyverse` allow us to do data wrangling in a fast, efficient, and high-level manner, which can have dramatic consequence for ease and speed with which we analyse data.

This course is aimed at anyone who is involved in real world data analysis, where the raw data is messy and complex.

Data analysis of this kind is practiced widely throughout academic scientific research, as well as widely throughout the public and private sectors.

You can sign up for this course at any point within the live period until 3 working days prior to the course commencing.

Course Description

The course will cover these key topics:

reading in data into R using tools such as readr and readxl
wrangling with the powerful `dplyr` R package, focusing on filtering observations, selecting and modifying variables, and other major data manipulation operations
summarising data in `dplyr` using descriptive statistics
merging and joining data independent data frames
pivoting and reshaping data using the `tidyr` R package

During the course you’ll:

gain a comprehensive practical introduction to data wrangling using R and its complementary tools and interrelated packages, such as tidyverse, dplyr, tidyr, and purr
discover how to read data of different types into R, and cover in detail all the dplyr tools such as, select, filter, and mutate
learn how to use pipe operator (%>%) to create data wrangling pipelines that take raw messy data on the one end and return cleaned tidy data at the other
discover how to perform descriptive or summary statistics on data using dplyr's summarise and group_by functionalities
learn how to combine data frames, including concatenating all data files in a folder and use SQL operations to merge information in different data frames.
develop an understanding of how to "pivot" data from a "wide" to "long" format and back using tidyr's pivot_longer and pivot_wider

What will I gain?

By the end of the course, you’ll be able to read messy and unstructured data into R and apply the principles of data wrangling to convert these datasets into optimally structured formats.

These data wrangling techniques will help with expediting data analysis tasks in a fast, efficiently robust, and to a high-level.

On completion of at least 80% of the course, you’ll receive a certificate of attendance.

Where you'll learn: The course is delivered through interactive online workshops via Zoom.

It will be practical, hands-on, and workshop based.

There will be some brief lecture style presentations throughout, i.e., using slides or blackboard, to introduce and explain key concepts and theories.

Throughout the course, and we will use real-world data sets and coding examples.

Tutor Profile: Mark Andrews is an Associate Professor at Nottingham Trent University whose research and teaching is focused on statistical methodology in research in the social and biological sciences.

He is the author of 2021 textbook on data science using R that is aimed at scientific researchers, and has a forthcoming new textbook on statistics and data science that is aimed at undergraduates in science courses.
