R自定義軟件包從文件錯誤安裝

Question

我一直在爲我的計算機在家裏的一個模擬項目工作R包，我已經使用RStudio來構建併成功安裝它。然而另一臺機器在我有麻煩......如果我嘗試建立RStudio，這也將其安裝過一個二進制大學，我得到一個錯誤，如果我只是編譯源得到它的工作原理是.tar.gz ，但是當我來安裝時，我再次得到錯誤。下面是兩次出現錯誤的讀數。我認爲這是與庫，但爲什麼這將是不同的，以我家裏的電腦我不知道，我不是程序員，這臺機器上安裝完全相同的方式R和RTools和RStudio作爲我個人機。 - 我有管理員訪問了幾天。

Answer 1

幾天前我遇到過類似的錯誤。這是因爲你正在安裝到這個目錄：

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

我想它連接到網絡驅動器。你應該做的是去那個網絡驅動器，並明確地複製地址，如

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

然後用它來指定安裝時的庫位置。例如：

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

或者嘗試devtools，解開你的焦油球和做類似：

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/"') 

這是我如何解決我的問題。

Answer 2

我發現問題與R腳本中roxygen註釋中的Windows路徑反斜槓有關。解決方案是將反斜槓更改爲單個正斜槓。 例子：本來我roxygen信息是這樣的：

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

導致此警告消息：

* 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) 

的線索是，文本是橙色的，而不是在RStudio了慣用的藍色。

因此，將反斜槓改爲正斜槓，並且不會生成警告消息，並且所有roxygen註釋現在都是藍色。

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