从github存储库安装开发版R包时如何指定lib目录

要添加指定的库路径devtools,我们需要使用with_libpaths()

争论的with_libpaths()是,with_libpaths(new, code)

以下是使用的示例with_libpaths(),

library(devtools)
with_libpaths(new = "/usr/lib/R/site-library/", install_github('rCharts', 'ramnathv'))

礼貌:哈德利,在这里 :)

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

这里有更多解释

install_github采取...传递给的论据devtools::install.devtools::install有一个args论点.

args
要传递给R CMD安装的附加命令行参数的可选字符向量.默认为选项"devtools.install.args"的值.

R CMD install 采取图书论证

 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

所以以下应该有效:

devtools::install_github("repo", args = c('--library="./mypath/gdfgdg/"'))

但它似乎没有取代呼叫 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/"
