从Github安装R软件包时遇到问题

Question

Please be patient with me as I'm a total noob, but I'm really trying to learn.

I'm trying to make a choropleth map for my country, and found an R package on Github that handles it excellently. However, I'm working on a university computer and I don't have write privileges on any drive but M://, so whenever the package tries to install on C:// it obviously throws an error. This hasn't been a problem since I can just specify a libpath as an argument on install.packages, but devtools::install_github does not seem to have such an argument.

I tried using

with_libpaths(new = "M:\R\win-library\3.2", install_github('diegovalle/mxmaps'))

But I got an error message saying

with_libpaths' is deprecated. Use 'withr::with_libpaths' instead.

I take this to mean that I need to install the "withr" package in order to use that? However, I keep getting errors when trying to install that package. First, I got

Warning in install.packages : installation of package 'withr' had non-zero exit status

because of the not having access to C:// issue. I usually bypass this by installing directly from the binaries, but when I try that it tells me

"Warning in install.packages : package 'withr' is not available (for R version 3.2.2)".

Other than updating my version of R (which will be a nighmare since I don't have installation privileges on this machine), how else can I either install withr or find another way to specify the directory to install the package from github?

我建议您使用3.4的最新版本。上述所有软件包均在最新版本下提供。

Two ways to set local library paths (at least on Linux running R 3.5.3):

(1) At the beginning of your script, set the the .libPaths option to your local library path, ie: .libPaths("M:\\R\\win-library\\3.2")

(2) Add to your .Renviron file a line that specifies your local library path: ie: R_LIBS="M:\\R\\win-library\\3.2"

Note: For (1) You will need to manually run every time you start a new R session, whereas (2) will be set automatically when R starts.
