R自定义软件包从文件错误安装

Question

我一直在为我的计算机在家里的一个模拟项目工作R包，我已经使用RStudio来构建并成功安装它。然而另一台机器在我有麻烦......如果我尝试建立RStudio，这也将其安装过一个二进制大学，我得到一个错误，如果我只是编译源得到它的工作原理是.tar.gz ，但是当我来安装时，我再次得到错误。下面是两次出现错误的读数。我认为这是与库，但为什么这将是不同的，以我家里的电脑我不知道，我不是程序员，这台机器上安装完全相同的方式R和RTools和RStudio作为我个人机。 - 我有管理员访问了几天。

Answer 1

几天前我遇到过类似的错误。这是因为你正在安装到这个目录：

'\\ueahome5/ressci17/yrq12edu/data/Documents/R/win-library/2.15/speEaR' 

我想它连接到网络驱动器。你应该做的是去那个网络驱动器，并明确地复制地址，如

'M:/ressci17/yrq12edu/data/Documents/R/win-library/2.15/' 

然后用它来指定安装时的库位置。例如：

install.packages("speEaR_1.0.tar.gz", repos=NULL, type="source",lib='U:/ressci17/yrq12edu/data/Documents/R/win-library/2.15/') 

或者尝试devtools，解开你的焦油球和做类似：

library(devtools) 
has_devel() ## check if your Rtools are properly installed 
check('speEaR') 
##build('speEaR') 
install("speEaR",args='-l "U:/ressci17/yrq12edu/data/Documents/R/win-library/2.15/"') 

这是我如何解决我的问题。

Answer 2

我发现问题与R脚本中roxygen注释中的Windows路径反斜杠有关。解决方案是将反斜杠更改为单个正斜杠。 例子：本来我roxygen信息是这样的：

#' Performs a search in MS Windows file system for all files in the 
#' `C:\USERS\MYNAME` directory, and all directories below that 

导致此警告消息：

* installing to library 'C:/Users/MYNAME/Documents/R/win-library/3.2' 
* installing *source* package 'whatever' ... 
** R 
** preparing package for lazy loading 
** help 
Warning: C:/Users/MYNAME/Documents/R/CODE/whatever/man/func.Rd:11: unknown macro '\USERS' 
Warning: C:/Users/MYNAME/Documents/R/CODE/whatever/man/func.Rd:11: unknown macro '\MYNAME' 
*** installing help indices 
** building package indices 
** testing if installed package can be loaded 
* DONE (whatever) 

的线索是，文本是橙色的，而不是在RStudio了惯用的蓝色。

因此，将反斜杠改为正斜杠，并且不会生成警告消息，并且所有roxygen注释现在都是蓝色。

#' Performs a search in MS Windows file system for all files in the 
#' `C:/USERS/MYNAME` directory, and all directories below
