Introduction

Welcome to the USC Biostats R Handbook. These chapters serves as a catalog of information that we find valuable for students, staff and faculty to know about if they are writing R code and packages.

It is recommended that everybody read the chapters about

• Coding Standards,
• High Performance Computing and,
• Parallel computing

These chapters should provide coding standards we wish to adhere by and methods of how to get your code running on HPC and in parallel to improve speed.

If you are having problems with speed then take a look at

• Profiling and
• Slow R patterns

to learn how to profile your code, and see examples of easy speedups.

If you are about to turn your code into a package then the following chapter is worthwhile to read

• R packages
