Currently:
==========
\arguments{
[...]
  \item{xlab, ylab}{
[...]
Default to the \sQuote{call names} of \code{x} or \code{y},
or to \code{""} if these where unspecified.}
                         ^^^^^

Should read:
============

[...]
  \item{xlab, ylab}{
[...]
Default to the \sQuote{call names} of \code{x} or \code{y},
or to \code{""} if these were unspecified.}
