This tutorial introduces (1) R as a programming language and (2) R tutorial available on our wiki.
Prerequisites
The workshop aimed at individuals who apply statistics and statistical packages. It is assumed those individuals will have developed some good understanding of statistical techniques. However, some statistical resources can be found in the introduction of the R tutorial.
Aims
Provide some background information about R programming language
Demonstrates how to use R studio console, help and R Notebooks
Demonstrate how large datasets can analysed using R and data hubs
Provide an overview of the R tutorial for DataSHIELD users.
Tutorial Plan
The audience was encouraged to ask questions during the workshop. Those were addressed and answered at the time. If any individuals have any questions, they can contact us and we will respond to them as quickly as possible.
