从github安装ggbiplot

Question

我正在尝试从格比图安装Github的开发版本。在安装过程中，我收到以下错误消息：

library(devtools)
install_github("ggbiplot", "vqv")

想办法解决这个问题吗。提前感谢您的帮助和时间。

编辑

在从Github下载之后，也尝试

install.packages("vqv-ggbiplot-2623d7c.tar.gz", repos=NULL, type="source")

产生了这个错误消息。

Answer 1

这是因为您的Rlib路径中有一个空格：C:/Users/Muhammad Yasseen/R/win-library/2.14。

请参见第一个错误日志中的警告消息是如何

running command '"C:/PROGRA~1/R/R-214~1.2/bin/i386/R" CMD INSTALL 
C:\Users\MUHAMM~1\AppData\Local\Temp\Rtmpsx4n5u/ggbiplot_0.5.tar.gz
--library=C:/Users/Muhammad Yaseen/R/win-library/2.14' 
had status 1 

特别是--library=C:/Users/Muhammad Yaseen/R/win-library/2.14。

这应该是--library="C:/Users/Muhammad Yaseen/R/win-library/2.14"来处理空间。

使用install.packages会为您处理引号--查看第二条警告消息(使用install.packages时)是怎样的

running command 'C:/PROGRA~1/R/R-214~1.2/bin/i386/R CMD INSTALL 
-l "C:/Users/Muhammad Yaseen/R/win-library/2.14"   
"vqv-ggbiplot-2623d7c.tar.gz"' had status 1 

-l "C:/Users/Muhammad Yasseen/R/win-library/2.14"在它周围有引号，所以您不会得到相同的错误。

我快速查看了install-github源代码，并通过以下方法构造了R CMD INSTALL命令：

paste("CMD INSTALL ", built_path, " --library=", .libPaths()[1], sep="")

看看在空格情况下，它如何不用双引号环绕.libPaths()[1]？我猜这是你的问题。

至于修复--在由install.packages()生成的tar文件上使用git (如报告的这里)似乎出现了错误。所以，你可以：

• 将R库位置更改为没有空格的位置
• 解压缩.tar.gz文件(我不知道是什么软件在Windows上这样做)，然后从提取的目录而不是从.tar.gz安装。

Answer 2

您不能解压缩.tar.gz，因为它比您抓取文件更快地清理该文件(我已经看到它出现并再次被删除)。如果我错了，请纠正我，但我也不能从github获得devtools，原因也是一样的：
