将R包安装到特定目录

Question

我尝试使用此代码将R包安装到我存储R包的目录中.

install.packages("zoo", lib="/data/Rpackages/")

我收到了这条警告信息:

install.packages("zoo",lib ="/ data/Rpackages /")中的警告:'lib ="/ data/Rpackages /"'不可写

其次,我如何.Renviron在我们的家庭区域创建一个文件并添加该行R_LIBS=/data/Rpackages/？

你如何真正摆脱警告局面？是否有更好的方法(在R Studio菜单中)Session-> Interrupt R并终止R会话？我试过CTRL-C.

> install.packages("car", lib="/my R packages/")
Warning in install.packages :
  'lib = "/my R packages/"' is not writable

我解决这个问题的方法是使用'Packages'窗口在R Studio中加载包,然后执行以下操作:

> install.packages("car")
Installing package into ‘C:/Users/33386/Documents/R/win-library/3.1’
(as ‘lib’ is unspecified)
trying URL 'http://cran.rstudio.com/bin/windows/contrib/3.1/car_2.0-21.zip'
Content type 'application/zip' length 1332800 bytes (1.3 Mb)
opened URL
downloaded 1.3 Mb

package ‘car’ successfully unpacked and MD5 sums checked

The downloaded binary packages are in
    C:\Users\33386\AppData\Local\Temp\RtmpKWnZD4\downloaded_packages
