Steven Sanderson compares two functions:
Both grep() and grepl() are functions in R that help us search for patterns in text. Think of them as detectives looking for clues in a big pile of words!
grep(): This function is like a pointer. It tells you where it found the pattern you’re looking for.grepl(): This one is more like a yes/no checker. It tells you if the pattern exists or not.
Read on for examples of each.
