Introduction to R

Getting Started

This lesson assumes no prior experience with the tools covered in the workshop. Participants should bring their laptops and plan to participate actively.

This lesson is part of a workshop that uses data hosted on an Amazon Machine Instance (AMI). Workshop participants will be given information on how to log-in to the AMI during the workshop. Learners using these materials for self-directed study will need to set up their own AMI. Information on setting up an AMI and accessing the required data is provided on the Metagenomics Workshop Setup page.
