为Windows创建R pacakge -ERROR：包xxx的编译失败

我无法在 Windows上为R构建虚拟测试包.
为了测试目的,在R终端,我输入：

a=rnorm(10)
package.skeleton("pkgtest")

然后我在这个虚拟包上运行R CMD检查pkgtest并得到错误

* using R version 2.12.0 (2010-10-15)
* using platform: i386-pc-mingw32 (32-bit)
* using session charset: ISO8859-1
* checking for file 'pkgtest/DESCRIPTION' ... OK

* this is package 'pkgtest' version '1.0'
* checking package dependencies ... OK
* checking if this is a source package ... OK
* checking for executable files ... OK
* checking whether package 'pkgtest' can be installed ... ERROR Installation failed.

编辑,完整的日志文件：

* installing *source* package 'pkgtest' ...
** libs
cygwin warning:

  CYGWIN environment variable option "nodosfilewarning" turns off this warning.

`* removing 'C:/DOCUME~1/xxxx'`

就这些.我在数据文件夹中有一个数据,所以它不是空的. Rd文件实际上可以通过Rcmd rd2pdf编译为pdf,其标题不为空.

我错过了一些非常基本的错误吗？我安装了Rtools2.12.我甚至有包内联和Rcpp安装并运行示例很好.
为了测试我的R环境设置,我下载了Rcpp源代码包并对Rcpp进行了R cmd检查,它没问题.

首先,你是否按照package.skeleton的输出要求你这样做？：

> a=rnorm(10)
> package.skeleton("pkgtest")
Creating directories ...
Creating DESCRIPTION ...
Creating Read-and-delete-me ...
Saving functions and data ...
Making help files ...
Done.
Further steps are described in './pkgtest/Read-and-delete-me'.

特别是最后一行.

你没有引用完整的CHECK日志,我得到：

$R CMD check pkgtest
* checking for working pdflatex ... OK
* using log directory '/home/gavin/tmp/pkgtest.Rcheck'
* using R version 2.11.1 Patched (2010-08-17 r52767)
* using session charset: UTF-8
* checking for file 'pkgtest/DESCRIPTION' ... OK
* checking extension type ... Package
* this is package 'pkgtest' version '1.0'
* checking package dependencies ... OK
* checking if this is a source package ... OK
* checking for executable files ... OK
* checking whether package 'pkgtest' can be installed ... ERROR
Installation failed.
See '/home/gavin/tmp/pkgtest.Rcheck/00install.out' for details.

所以你应该去检查它提到的.out文件的内容.我在该文件中有以下内容：

$cat /home/gavin/tmp/pkgtest.Rcheck/00install.out
* install options are ' --no-html'

* installing *source* package ‘pkgtest’ ...
** R
** data
** preparing package for lazy loading
** help
Warning: ./man/pkgtest-package.Rd:34: All text must be in a section
Warning: ./man/pkgtest-package.Rd:35: All text must be in a section
*** installing help indices
Error in Rd_info(db[[i]]) : 
  Rd files must have a non-empty title.
See chapter 'Writing R documentation' in manual 'Writing R Extensions'.
* removing ‘/home/gavin/tmp/pkgtest.Rcheck/pkgtest’

一旦你看到包源,这是相当不言自明的.

你至少需要：

> a=rnorm(10)
> package.skeleton(name = "pkgtest",list = "a")

然后你应该注意,你必须编辑Rd文件.这是一个设计特性,prompt()和package.skeleton()不会创建有效的Rd文件,以使包作者编写其包的最低文档.
