What you'll learn

  • Implement conditional program logic using if-else structures, nested conditional statements, `is` functions, and the `%in%` membership operator.

  • Control execution flow with for and while loops alongside functional vectorized loop alternatives like `apply()`, `lapply()`, and `sapply()`.

  • Structure reusable code by defining custom functions with dynamic scope, lazy evaluation rules, and flexible ellipsis `(...)` arguments.

  • Data files for this course are provided in the first course of this specialization, "R Programming: Setup and Data Processing".

In this course, you'll continue to develop your R programming skills by writing conditional statements and loops—two of the most important constructs in any programming language. You'll also structure code for reuse by defining and calling functions, applying loop functions, and managing R packages.

This is the second course in a multi-course Specialization. All of the courses in this Specialization require that you have R and R Studio installed on a Windows PC. The course setup instructions provided in the first course go into more detail about the hardware and software requirements.

Like any modern programming language, R enables you to control the logical flow of a program. The main constructs for doing so are conditional statements and loops, which you'll implement in this lesson so that you can apply decision making to code.

Most languages excel at giving programmers the tools they need to make coding easier. Reusing code not only allows you to develop at a quicker pace, but it also makes your source code more readable. Inefficient and ugly code is incredibly difficult to maintain, so you'll leverage R's built-in reusable objects to avoid this pitfall

Frequently asked questions

To access the course materials, assignments and to earn a Certificate, you will need to purchase the Certificate experience when you enroll in a course. You can try a Free Trial instead, or apply for Financial Aid. The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.

When you enroll in the course, you get access to all of the courses in the Specialization, and you earn a certificate when you complete the work. Your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile.

Yes. In select learning programs, you can apply for financial aid or a scholarship if you can’t afford the enrollment fee. If fin aid or scholarship is available for your learning program selection, you’ll find a link to apply on the description page.
