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.
