R skills workshops: R Markdown and Building R packages

SSA Vic and Melbourne Integrative Genomics (MIG) are hosting a day of R skills workshops.

R is an interactive environment for data analysis and statistical modelling. When performing data analysis, you typically need to share your insights with others. In our morning workshop, you will learn how to share and communicate your findings with yourself and others using R Markdown. As you go further on your journey with R, you will write functions that you use to perform common tasks. In the afternoon workshop, you will learn how put these together into an R package, which makes them easier to use and very easy to share.

These are PAID workshops. You can choose to do half-day or full-day (both registrations include tea and lunch).


Outline

R Markdown (morning session, 9am to 12:30pm)
Presented by: Patrick Robotham & Nick Tierney

For a scientific report to be completely credible, it must be reproducible. The full computational environment used to derive the results, including the data and code used for statistical analysis should be available for others to reproduce.

R Markdown is a tool that allows you integrate your code, text and figures in a single file in order to make high quality, reproducible reports. A paper published with an included R Markdown file and data sets can be reproduced by anyone with a computer.

After completing this course, you will know how to:
- Create your own R Markdown document
- Create figures and tables that you can reference in text, and update with - your data
- Export your R Markdown document to PDF, HTML, and Microsoft Word
- Use keyboard shortcuts to improve workflow
- Cite research articles and generate a bibliography

We may, depending on time, also cover the following areas:
- Change the size and type of your figures
- Create captions for your figures, and reference them in text
- Cite research articles and generate a bibliography
- Debug and handle common errors

Building R packages (afternoon session, 1:30pm to 5pm)
Presented by: Damjan Vukcevic

You have developed a new statistical method. Now it is time to share it with the world.

The methods that actually get used in practice are those with readily available and user-friendly implementations. Writing and disseminating software is therefore a key skill for modern statisticians, one that is generally not taught widely. This course aims to fill the gap.

The R software environment is widely used for statistical analyses. One of its distinguishing features is the extensive range of R ‘packages’, which anyone can write and share via the internet. This used to be an intimidating process but modern tools have made it simple.

We begin our course with how to write a very basic package, and then show how to include documentation, examples and data. Further topics include: an efficient development workflow, managing relationships between packages, sharing your packages with others, and easy ways to manage packages (finding, installing, upgrading).

The following statistical concepts will be introduced: covariance and correlation, multiple linear regression, classification and prediction, cross-validation, selection of diagnostic or prognostic markers, l1 and l2 penalties in a regression framework. Each methodology will be illustrated on a case study (theory and application will alternate). Note that mixOmics is not limited to biological data only and can be applied to other type of data where integration is required.
