R自定义包从文件安装错误

4

我一直在为一个仿真项目开发一个 R 包。在家里的电脑上，我使用 RStudio 成功地构建和安装了它。然而，在大学的另一台机器上，我遇到了问题……如果我尝试在 RStudio 中构建二进制文件并安装它，就会出现错误。如果我只编译源代码以获取 .tar.gz 文件，则可以正常工作，但是当我尝试安装时，仍会出现错误。以下是两次出现的错误信息。我认为这与库有关，但为什么这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、RTools 和 RStudio 时与在个人电脑上完全相同。- 我有几天的管理员访问权限。

我发现问题与R脚本中roxygen注释中的Windows路径反斜杠有关。解决方法是将反斜杠改为单个正斜杠。例如：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

这个会导致出现以下警告信息：

* 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)

线索是在RStudio中，文本的颜色是橙色而不是通常的蓝色。

因此，将反斜杠改为正斜杠，就不会产生警告消息，并且所有roxygen注释现在都是蓝色的。

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

我几天前也遇到过类似的错误。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'

我猜它连接到了一个网络驱动器。你需要做的是去那个网络驱动器，明确地复制地址，如下所示：

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

然后在安装时使用它来指定库的位置。例如：

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

或者尝试使用开发工具，解压你的tar包并执行如下操作：

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。
