[Rd] Problem with creating links ("see also" section) in help files.

[Aleš Žiberna]

A link in one of my help files does not work. I have in this help file:
\seealso{\code{\link{crit.fun}}, \code{\link{opt.par}}, 
\code{\link{opt.random.par}}, \code{\link{opt.these.par}}, 
\code{\link{nkpartitions}}, \code{\link{nkpar}}, 
\code{\link{plot.check.these.par}} }

Everything in one row, the last link does not work. In another help 
file, I have:
\name{plot.mat}
\alias{plot.mat}
\alias{plot.crit.fun}
\alias{plot.opt.par}
\alias{plot.opt.par.mode}
\alias{plot.opt.more.par}
\alias{plot.opt.more.par.mode}
\alias{plot.check.these.par}

The last alias should corresponds to the link that does not work.

This is also produces a massage when building a binary package or 
installing a package:
  check.these.par                   text    html    latex   example chm
     missing link(s):  plot.check.these.par

Any ideas?

Best regards and thanks in advance for any suggestions,
