R help - May 2002 - Strange R CMD check \usage parse error

In running R CMD check I get an error I can't debug.  Would someone please
let me know if they spot a syntax error in the code below or if there is a
workaround for the parse error?  Thanks -Frank


Error in parse(file, n, text, prompt) : parse error
Error in codoc(package = "Hmisc") : cannot source usages in
documentation object 'plsmo'
Execution halted
* checking for undocumented arguments in \usage ... WARNING

\usage{

xlab, ylab,
      add=F, lty=1:nlev, col=par("col"), lwd=par("lwd"),
      iter=ifelse(length(unique(y))>2, 3, 0), bass=0, trim, 
      fun, group, prefix, xlim, ylim, 
      label.curves=T, datadensity=F, lines=T, ...)

       cex = superpose.symbol$cex, 
       font = superpose.symbol$font, 
       col = NULL, ...)
}

The usage checks convert to empty function declarations, so the syntax
error is in the converted version
  xyplot<-function (y ~ x | conditioningvars, groups,
        panel=panel.plsmo, type='b',
        label.curves=T,
        lwd = superpose.line$lwd,
        lty = superpose.line$lty,
        pch = superpose.symbol$pch,
        cex = superpose.symbol$cex,
        font = superpose.symbol$font,
        col = NULL, ...) NULL

You need to give the argument name for the first argument, ie
 	formula=y ~ x | conditioningvars
