Toss R Package-devtools

Today for some reason I intend to install R package Devtools, I use the XP platform, R3.2.1. At the beginning, download the Devtools package zip file, and then installs it in the R program Menu:packages, installpackages from local zip files, and then discovers that it requires a lot of front-facing packages to run, Instead, use the command install.packages ("Devtools"). It is recommended to select the Mirror china.beijing (the first in China), which is faster.

After a large pile of packages, run the library (devtools); Result Error:

Cannot find pointer _chsize_s in Msvcrt.dll

.../library/git2r/libs/i386/git2r.dll,loadlibrary failure:the specified procedure could not being found.

What the. Baidu A check, no answer, so Bing (r a lot of information Baidu Chinese can not find the ~), found that some people say is version and XP conflict, with Win7 or other version of the Devtools is good.

See: Http://stackoverflow.com/questions/30633894/r-unable-to-load-devtools-in-r-3-2-0-under-windows-xp-32-bit

So went to Https://cran.r-project.org/download R-3.0.3 again try, Mom, this will also report:

To build R packages, download and install Rtools 3.1 from http://cran.r-project.org/bin/windows/Rtools/

See if you can download a specific version of the package, found a lower version of the GIT2R, the local installation after the run Devtools, the version is incompatible ~ ~

Want to download a specific version of Devtools directly in the R3.2.1, found that install.packages can not do, to use Devtools install_version (), but I am now devtools can not get up ￥@#%%

Too frustrating, the home of the old XP temporarily do not play this stuff, tomorrow with another Win7 try again.
