The documentation for the function require is incorrect.

The file library.Rd has in its arguments section

  \item{quietly}{a logical.  If \code{TRUE}, a warning will not be
      printed if the package cannot be found.}

which is incorrect, as a warning message is always given if the package 
is not found.
Should be something like

  \item{quietly}{a logical.  If \code{TRUE}, a message confirming
      package loading is not printed.}

also, the details section has

  \code{require} is designed for use
  inside other functions; it returns \code{FALSE} and optionally gives a
  warning, rather than giving an error, if the package does not exist.

The sentence after the semi-colon is also appears to be incorrect, as
require calls library with logical.return = TRUE.
Should be something like 

  \code{require} is designed for use
  inside other functions; it returns \code{FALSE} and gives a warning
  if the package does not exist.
