Intermediate R Data Camp

Overview

Context

Intermediate R is the next stop on your journey in mastering the R programming language. 

In this Intermediate R course offered by Data Camp, you will learn about conditional statements, loops, and functions to power your own R scripts. Next, make your R code more efficient and readable using the apply functions. 

Finally, the utilities chapter gets you up to speed with regular expressions in R, data structure manipulations, and times and dates. This course will allow you to take the next step in advancing your overall knowledge and capabilities while programming in R.

What you'll learn:

• Apply mathematical and data-structure utility functions (abs(), round(), seq(), rep(), sort(), str()) to transform and inspect R objects.
• Create, convert, and compute with R date and time objects using Sys.Date(), Sys.time(), as.Date(), and as.POSIXct().
• Use lapply(), sapply(), and vapply() to apply functions over lists/vectors and reason about simplification behavior and return types.
• Use regular expression functions (grepl(), grep(), sub(), gsub()) to detect, extract, and replace text patterns in character data.
• Write custom R functions with arguments, defaults, control flow, and safe processing logic using if, else if, and return().
