为Windows编译R-pkakge -ERROR：编译包xxx失败

Question

我无法在Windows上为R构建虚拟测试包。 用于测试目的，在R端子，我输入：

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

然后我运行该虚拟包R CMD check pkgtest并得到了错误，如

* 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'` 

就是这样。我在数据文件夹中有一个数据a，所以它不是空的。 Rd文件实际上可以编译成pdf格式，编号为Rcmd rd2pdf，其标题不为空。

我是否错过了这个错误非常基本的东西？我安装了Rtools2.12。我甚至有包inline和Rcpp安装和运行的例子很好。 为了测试我的R环境设置，我下载了Rcpp源码包并在Rcpp上做了R cmd check，它没有问题。

Answer 1

是的，很多，如果你所做的只是以上记录的步骤。

首先，你有没有做到从package.skeleton输出要求你？：

> 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'. 

特别是最后一道防线。

你不引用全面检查日志，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.out文件它提到的内容。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’ 

一旦您查看软件包源代码，这一点是不言自明的。

您至少需要：

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

然后你要注意，你必须编辑的Rd文件。这是一个设计功能prompt()和package.skeleton()不会创建有效的Rd文件来让包作者编写它们包的最小文档。

Answer 2

您需要查看下一行中未列出的文件中的错误。

当我尝试追溯你的脚步，我也得到一个错误：

/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$ 

为package.skeleton()是有意义的，你需要给它一个或多个功能，数据对象，...你做不。
