R/S System: Advanced Programming
This advanced course is designed for people who use R or S-Plus in their day-to-day work and want to maximize the efficiency of their programs. Participants will learn in depth advanced programming techniques that are available in R and S-Plus. This course will improve your general strategies and extend your programming skills.
Benefits
This two-day course will introduce participants to many programming techniques and tools. In addition a special session dedicated to making S-Plus functions more efficient will focus on "fast objects" and "fast functions". The advanced programming techniques include object orientation, classes, inheritance and methods
