How to specify lib directory when installing development version R Packages from github repository
提问by Manoj G
In Ubuntu, I am installing all the R packages in the directory, /usr/lib/R/site-libraryby specifying liboption in install.packages().
在 Ubuntu 中，我/usr/lib/R/site-library通过lib在install.packages().
But when I try to install the development version of the R packages using, install_github(), it always installs in a local repository of the system user.
但是当我尝试使用 安装 R 包的开发版本时install_github()，它总是安装在系统用户的本地存储库中。
.libPaths()has 4 directories including the local repository. So, I have 2 questions,
.libPaths()有 4 个目录，包括本地存储库。所以，我有2个问题，
Will it install in any of the other 3 repositories if i remove the local repository from
.libPaths()?Is there any way to specify installation library path in
install_github()?
如果我从中删除本地存储库，它会安装在其他 3 个存储库中的任何一个
.libPaths()吗？有什么办法可以指定安装库路径
install_github()吗？
I am using Ubuntu 12.04 64bitand R 3.0.1
我正在使用Ubuntu 12.04 64bit和R 3.0.1

Unable to remove the local repository from
.libPaths()If I try to install using
install_github()in RStudio, it installs in thelocal repositorysincelibis not specified.If I try to install using
install_github()as non-root user, it installs in thelocal repositorysincelibis not specified.If I try to install using
install_github()as root user, it installs in the/usr/local/lib/R/site-librarysincelibis not specified.
无法从中删除本地存储库
.libPaths()如果我尝试
install_github()在RStudio 中安装 using ，它会安装在local repository因为lib未指定的位置。如果我尝试使用安装
install_github()作为非root用户，它在安装local repository，因为lib没有指定。如果我尝试使用安装
install_github()作为根用户，它在安装/usr/local/lib/R/site-library，因为lib没有指定。
Is there any to specify installation lib?
有什么要说明的installation lib吗？

To add specified library paths in devtools, we need to use with_libpaths()
要在 中添加指定的库路径devtools，我们需要使用with_libpaths()
Arguments for with_libpaths()are, with_libpaths(new, code)
的论据with_libpaths()是，with_libpaths(new, code)
Following is an example for using with_libpaths(),
以下是使用的示例with_libpaths()，
library(devtools)
with_libpaths(new = "/usr/lib/R/site-library/", install_github('rCharts', 'ramnathv'))
Courtesy: Hadley, here:)
礼貌：哈德利，在这里:)
And other than with_libpaths(), there are more options for in devtools::with_something()
而且比其他with_libpaths()，也有更多的选择devtools::with_something()
in_dir: working directory
with_collate: collation order
with_envvar: environmental variables
with_libpaths: library paths, replacing current libpaths
with_lib: library paths, prepending to current libpaths
with_locale: any locale setting
with_options: options
with_path: PATH environment variable
with_par: graphics parameters

install_githubtakes a ...argument that passes to devtools::install. devtools::installhas an argsargument.
install_github接受一个...传递给的参数devtools::install。devtools::install有一个args论点。
args
An optional character vector of additional command line arguments to be passed to R CMD install. This defaults to the value of the option "devtools.install.args".
args
要传递给 R CMD 安装的附加命令行参数的可选字符向量。这默认为选项“devtools.install.args”的值。
R CMD installtakes a library argument
R CMD install接受一个库参数
Options:
-h, --help print short help message and exit
-v, --version print INSTALL version info and exit
-c, --clean remove files created during installation
--preclean remove files created during a previous run
-d, --debug turn on debugging messages
and build a debug DLL
-l, --library=LIB install packages to library tree LIB
So the following should work:
所以以下应该工作：
devtools::install_github("repo", args = c('--library="./mypath/gdfgdg/"'))
however it doesnt appear to be replacing the call to R CMD install
但是它似乎并没有取代对 R CMD install
"C:/PROGRA~1/R/R-31~1.0/bin/x64/R" --vanilla CMD INSTALL \
"C:\Users\john\AppData\Local\Temp\RtmpucrXMD/RSelenium_1.3.2.tar.gz" \
--library="C:/Users/john/Documents/R/win-library/3.1" --install-tests \
--library="C:/Users/john/Desktop/"

This is more of a workaround, but I found a way using the command-line version of R.
这更像是一种解决方法，但我找到了一种使用 R 的命令行版本的方法。
Starting from Ubuntu:
从 Ubuntu 开始：
sudo -i R
sudo -i R
the trick (I found) is to use -ioption
诀窍（我发现）是使用-i选项
Then from R:
然后从 R：
.libPaths()
.libPaths()
my local R directory does not appear; the default directory is the one that I want.
我的本地 R 目录没有出现；默认目录是我想要的目录。
Then, I install.packages()or install_github()with impunity.
那么，我install.packages()还是install_github()逍遥法外。
Hope this helps,
希望这可以帮助，
