Answer / Sheetal Kumari
The R programming language provides two ways to load packages: library() and require(). The main difference lies in how they handle errors. library() does not produce an error when a package is not found, it simply returns NULL. On the other hand, require() produces an error if the package is not found, which can be useful for scripting since scripts should generally fail fast rather than continue with unavailable packages.
