[R] Glitch when creating online help

Ah, I think I've solved it. Apparently \describe needs to have a newline
before it, or things get funny. Thus


\arguments{
    \item{item1}{ This is item 1. }
    \item{itemlist}{ Here is a list.
        \describe{
        \item{subitem1}{Item 1 of the list.}
        \item{subitem2}{Item 2 of the list.}
        }
    }
}


works fine. OTOH,


\details{ Here is another list. \describe{
    \item{subitem1}{Item 1 of the list.}
    \item{subitem2}{Item 2 of the list.}
    }
}


(no nesting of \describe within an \item) gives the same glitch as
described below. (Maybe I need to brush up on my TeX....)

Hi,

I'm writing up the online help for a package I'm developing (in-house
only, sorry), and I've come across an odd glitch when trying to nest a
list inside the "arguments" section of the .Rd file. I was just
wondering if anyone could provide some insights. I'm using R 2.2.0 on
Windows XP, along with ActivePerl 5.8.7 (build 815), MikTeX 2.4, and the
tools downloaded from http://www.murdoch-sutherland.com/Rtools/ .

Here is some code to reproduce the glitch. First, in R:

f <- function(x) x
package.skeleton("foo", list="f")

This creates the package skeleton, with a template f.Rd provided. Edit
f.Rd to contain


================
\name{f}
\alias{f}
\title{ ~~function to do ... ~~ }
\description{
  ~~ A concise (1-5 lines) description of what the function does. ~~
}
\usage{f(x)}
\arguments{
    \item{item1}{ This is item 1. }
    \item{itemlist}{ Here is a list. \describe{
        \item{subitem1}{Item 1 of the list.}
        \item{subitem2}{Item 2 of the list.}
        }
    }
    \item{item3}{ This is the item after the list. }
}
================


Then at the command prompt:

R CMD INSTALL --build foo

Once the package has been created, in R type:

library(foo)
?f

The result looks like


================
f                    package:foo                    R Documentation

~~function to do ... ~~

Description:

     ~~ A concise (1-5 lines) description of what the function does. ~~

Usage:

     f(x)

Arguments:

   item1: This is item 1. 

itemlist: Here is a list.  .in +5

     subitem1 Item 1 of the list.

     subitem2 Item 2 of the list.

   item3: This is the item after the list.

================


Note the ".in +5" at the top of the nested list. This is only in the
online help within R, not the html version.
