WORKSHOP: Multivariate analysis of microbiome data with mixOmics

This workshop is a short introduction to dimension reduction methods, including Projection to Latent Structures Discriminant Analysis (PLS-DA) to analyse microbiome count data. We will cover the basic principles of data processing (from a table of count), to data exploration and identification of a microbial signature to discriminate different sample groups. We will use the R package mixOmics and one or two case studies (see also for more details about the package and the workshops we run).

Key words: R, discriminant analysis, microbial signatures

Requirements: Software requirements: Install the latest version of mixOmics, as described here: on your laptop. Alternatively, you can sign for a free RStudio cloud account ( ) and start the installation from there.

Assumed knowledge: A good working knowledge in R programming (e.g. handling data frame, perform simple calculations and display simple graphical outputs) is essential to fully benefit from the workshop. The course covers both theory and hands-on practice, with the opportunity to analyse your own data (if you have your data already processed as a table of counts!).

Relevance: The workshop will be relevant to those interested in analysing microbiome data, and in understanding the particular characteristics of those data.
