Course Description

R code contain a lot of parentheses in case of a sequence of multiple operations. When you are dealing with complex code, it results in nested function calls which are hard to read and maintain. The magrittr package by Stefan Milton Bache provides pipes enabling us to write R code that is readable.

What will I learn?


After completing this course, you should be able to:

  • use the following pipe operators
    • %>%
    • %$%
    • %<>%
  • clearly express a sequence of multiple operations by:
    • structuring operations from left to right
    • avoiding
      • nested function calls
      • intermediate steps
      • overwriting of original data
    • minimizing creation of local variables


Self Paced Online Courses


Our online self paced courses are designed to allow participants to learn at their convenience. Learning outcomes are clearly defined and enhanced by the use of byte sized videos, PPTs, assignments, quizzes, suggested reading and case studies. Participants can take advantage of the discussion forum to discuss with their peers and the instructors to enhance their learning experience.
