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().

    Quite the addition of information from the basic R course. There are a LOT of commands to remember, but the user interface was key in learning.
