为Windows创建R pacakge -ERROR：包xxx的编译失败

Question

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 check 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
* 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.

编辑 ，完整的日志文件：

* installing *source* package 'pkgtest' ...
** libs
cygwin warning:
  MS-DOS style path detected: C:/R/R-212~1.0/etc/i386/Makeconf
  Preferred POSIX equivalent is: /cygdrive/c/R/R-212~1.0/etc/i386/Makeconf
  CYGWIN environment variable option "nodosfilewarning" turns off this warning.
  Consult the user's guide for more details about POSIX paths:
    http://cygwin.com/cygwin-ug-net/using.html#using-pathnames
ERROR: compilation failed for package 'pkgtest'
`* removing 'C:/DOCUME~1/xxxx'` 

就这些。 我有一个数据a数据文件夹，所以它不是空。 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inline和Rcpp并运行示例很好。 为了测试我的[R环境设置，我下载RCPP源码包，做了R cmd check上Rcpp ，会开得不错。

Answer 1

是的，如果您所做的只是上面记录的步骤，那就很多了。

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。

Answer 2

您需要查看未显示的下一行中列出的文件中的错误。

当我试图回溯你的步骤时，我也收到一个错误：

/tmp/pkgtest$ r -e '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'.
/tmp/pkgtest$ R CMD INSTALL pkgtest/
* installing to library ‘/usr/local/lib/R/site-library’
* installing *source* package ‘pkgtest’ ...
** data
** help
Warning: /tmp/pkgtest/pkgtest/man/pkgtest-package.Rd:33: \
        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 ‘/usr/local/lib/R/site-library/pkgtest’
/tmp/pkgtest$ 

要使package.skeleton()有意义，您需要为它提供一个或多个函数，数据对象，...您没有。
