I need to compare two string, for example i have data <- c('"Trafik kembali lancar di kedua - dua arah. Selamat memandu","Kemalangan motorsikal di Km 224.8 utara dari Simpang Ampat ke Pedas Linggi. Tiada laluan terhalang.").
i want to make a comparison that says
if there is a word Pedas in data return heavy traffic else return traffic clear
To clarify, R is the language, and RStudio is just the IDE (see FAQ below for disambiguation). Since this question isn't about the IDE itself, I'm going to move it to #general.
What you're describing sounds like a good use-case for grepl() or a similar string-matching function which:
search for matches to argument pattern within each element of a character vector
Hi @akmalirham! The function you're looking for is regexpr() (r after p, not p after r). It's part of the base, so if you have the name right you oughtn't need a package to use it
