R for Biologists
Author: Marco Martinez
This material is intended as an introductory guide to data analysis with the R system, to assist in statistical computing training for life science researchers. It was produced as companion material for a seminar (R Tutorial for Life Sciences) given at The University of Tennessee in the spring of 2009, sponsored by the National Institute for Mathematical and Biological Synthesis (NIMBioS).
The principal aim is to provide a step-by-step guide on the use of R to carry out statistical analysis and techniques widely used in the life sciences. In each section, there is a detailed explanation of a command in R, followed by a biological example with all the instructions (in red) needed to run the test and with the corresponding output in R (in blue). There is assumed previous knowledge in statistics and experimental design, essentially corresponding to a basic undergraduate introductory statistic course.
