R自定义包安装文件错误

Question

我一直在研究模拟项目的R包，在家里的计算机上我已经使用RStudio来成功构建和安装它。然而，在大学的另一台机器上我遇到了麻烦...如果我尝试在RStudio中构建一个二进制文件，它也安装它，我得到一个错误，如果我只是编译一个源来获得.tar.gz它的工作原理，但是当我来安装时，我又得到了错误。两次出现错误的读数如下。我认为这与图书馆有关，但为什么这会与我的家用电脑不同，我不知道，我不是程序员，并且在这台机器上安装R和RTools和RStudio与我个人完全一样机。 - 我有几天的管理员权限。

Answer 1

我几天前遇到过类似的错误。这是因为您正在安装到此目录：

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

我猜它已连接到网络驱动器。你应该做的是转到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/'

然后在安装时使用它来指定库位置。例如：

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

或尝试 devtools ，解压缩tar球并执行以下操作：

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/"')

这就是我解决问题的方法。

Answer 2

我发现问题与R脚本中的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。 示例：最初我的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

会产生此警告消息：

* 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)

线索是文本是橙色而不是RStudio中通常的蓝色。

因此，将反斜杠更改为正斜杠并且不会生成任何警告消息，并且所有的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
