R devel - Sep 2004 - Rd syntax error detected in CRAN daily checks

Please forgive me if you already received this.  I had an e-mail sending 
glitch this morning.


http://cran.r-project.org/src/contrib/checkSummary.html reported an 
error in Design.trans.Rd

* checking Rd files ... ERROR
Rd files with syntax errors:
   /var/mnt/hda3/R.check/r-devel/PKGS/Design/man/Design.trans.Rd:
     unterminated section 'alias'

The .Rd file is attached.  It begins with

\name{Design.trans}
\alias{Design.trans}
\alias{asis}
\alias{pol}
\alias{lsp}
\alias{rcs}
\alias{catg}
\alias{scored}
\alias{strat}
\alias{matrx}
\alias{\%ia\%}
\title{
Design Special Transformation Functions
}
\description{
This is a series of functions (\code{asis}, \code{pol}, \code{lsp},
....

No error is detected when I run CMD CHECK using the latest R-devel 
locally, using the 5 Sep 04 version.  I would appreciate assistance. 
Please cc: me because I get r-devel in digest format.

Thanks -Frank

\description{
This is a series of functions (\code{asis}, \code{pol}, \code{lsp}, \code{rcs},
\code{catg},
\code{scored}, \code{strat}, \code{matrx}, and \code{\%ia\%}) that set up
special attributes
(such as
knots and nonlinear term indicators) that are carried through to fits
(using for example \code{lrm},\code{cph}, \code{ols}, \code{psm}).
\code{anova.Design}, \code{summary.Design},
\code{plot.Design}, \code{survplot}, \code{fastbw}, \code{validate},
\code{specs},
\code{which.influence}, \code{nomogram.Design} and \code{latex.Design} use these
attributes to automate certain analyses (e.g., automatic tests of linearity
for each predictor are done by \code{anova.Design}). Many of the functions
are called implicitly.  Some S functions such as \code{ns} derive data-dependent
transformations that are not "remembered" when predicted values are
later computed, so the predictions will be incorrect. The functions listed
here solve that problem. 


\code{asis} is the identity transformation, \code{pol} is an ordinary
(non-orthogonal) polynomial, \code{rcs} is
a linear tail-restricted cubic spline function (natural spline, for which the
\code{rcspline.eval} function generates the design matrix),
\code{catg} is for a categorical
variable, \code{scored} is for an ordered categorical
variable, \code{strat} is for a stratification factor
in a Cox model, \code{matrx} is for a matrix predictor, and \code{\%ia\%}
represents
restricted interactions in which products involving nonlinear effects on both
variables are not included in the model.  \code{asis, catg, scored, matrx} are
seldom invoked
explicitly by the user (only to specify \code{label} or \code{name}, usually).

In the list below, functions \code{asis} through \code{strat} can have
arguments \code{x, parms, label, name} except that \code{parms} does not
apply to \code{asis, matrx, strat}.
}
\synopsis{
asis(\dots)
matrx(\dots)
pol(\dots)
lsp(\dots)
rcs(\dots)
catg(\dots)
scored(\dots)
strat(\dots)
\%ia\%(x1, x2)
}
\usage{
asis(x, parms, label, name)
matrx(x, label, name)
pol(x, parms, label, name)
lsp(x, parms, label, name)
rcs(x, parms, label, name)
catg(x, parms, label, name)
scored(x, parms, label, name)
strat(x, label, name)
\%ia\%(x1, x2)
}
\arguments{
\item{x}{
a predictor variable (or a function of one).  If you specify e.g.
\code{pol(pmin(age,10),3)}, a cubic polynomial will be fitted in
\code{pmin(age,10)}
(\code{pmin} is the S vector element--by--element function).
The predictor will be labeled \code{age} in the output, and plots with have
\code{age} in its original units on the axes. If you use a function such as
\code{pmin}, the predictor is taken as the first argument, and other arguments
must be defined in the frame in effect when predicted values, etc., are
computed.
}
\item{parms}{
parameters of transformation (e.g. number or location of knots).
For \code{pol} the argument is the order of the polynomial,
e.g. \code{2} for quadratic (the usual default). For \code{lsp} it is a
vector of knot locations (\code{lsp} will not estimate knot locations).
For \code{rcs} it is the
number of knots (if scalar), or vector of knot locations (if \code{>2}
elements).
The default number is the \code{nknots} system option if \code{parms} is not
given.
If the number of knots is given,
locations are computed for that number of knots.
For \code{catg}, \code{parms} is the
category labels (not needed if variable is an S category or factor variable). If
omitted, \code{catg} will use \code{unique(x)}, or \code{levels(x)} if \code{x}
is a \code{category}
or a \code{factor}.
For \code{scored}, \code{parms} is a
vector of unique values of variable (uses \code{unique(x)} by default).
This is not needed if \code{x} is an S \code{ordered} variable.
For \code{strat}, \code{parms} is the category labels (not needed if variable is
an S category variable). If
omitted, will use \code{unique(x)}, or \code{levels(x)} if \code{x} is
\code{category} or \code{factor}.
\code{parms} is not used for \code{matrix}.
}
\item{label}{
label of predictor for plotting (default = \code{"label"} attribute or
variable
name)
}
\item{name}{
Name to use for predictor in model. Default is name of argument to
function
}
\item{x1}{}
\item{x2}{two continuous variables for which to form a
  non-doubly-nonlinear interaction}
\item{\dots}{a variety of things}

# simple product interaction (doubly linear)

Frank,

The version of Design on CRAN

Package: Design
Version: 2.0-8
Date: 2004-05-31

has

\alias{%ia%}

and that has two unescaped comment characters which I guess you have
already fixed.

Brian

Brian Ripley pointed out that I had forgotten how old is the version of 
Design on CRAN.  The problem was already fixed.  Sorry for the bother -Frank
