一、 install.packages('REmap')无法安装package:错误:“无法与服务器建立连接”

解决方式:切换下载的镜像

方法一:在Rstudio菜单栏:tools-global options-packages中切换下载的镜像

方法二:修改文件,在安装文件夹中找到Rprofile.site文件,我的路径是D:\Program Files\R\R-3.4.1\etc,用记事本打开,在里面添加语句:

#setaCRANmirrorlocal({r<-getOption(“repos”)r[“CRAN”]<-“http://mirrors.tuna.tsinghua.edu.cn/CRAN/”options(repos=r)}

二、手动安装package

在网站:https://mirrors.tuna.tsinghua.edu.cn/CRAN/下载好需要的package

1.在R studio下,选择packages

2.选择Install

3.Install from栏选择Package Archive File(.zip;.tar.gz)

4.Package archive栏点击Browser,选择刚才下载的文件

5.点击Install,进行安装

致此,手动安装R包完成。安装提示如下

推荐第一种安装方式:因为第一种安装方式会自动安装依赖的包,而第二种方式,除了下载你想安装的包还要下载所有依赖的包,这就有一定的难度了。

补充:Rstudio安装packages时报错,原因可能是这样

最近接触R语言,安装好Rstudio后,需要安装R的第三方包mirt。

执行步骤如下:

正当满心欢喜地期待包的安装时,结果出现了下面的情况:

install.packages("mirt")WARNING:RtoolsisrequiredtobuildRpackagesbutisnotcurrentlyinstalled.PleasedownloadandinstalltheappropriateversionofRtoolsbeforeproceeding:https://cran.rstudio.com/bin/windows/Rtools/Installingpackageinto‘C:/Users/likailei/Documents/R/win-library/3.6'(as‘lib'isunspecified)Warningininstall.packages:unabletoaccessindexforrepositoryhttps://cran.rstudio.com/src/contrib:cannotopenURL'https://cran.rstudio.com/src/contrib/PACKAGES'Warningininstall.packages:package‘mirt'isnotavailable(forRversion3.6.0)Warningininstall.packages:unabletoaccessindexforrepositoryhttps://cran.rstudio.com/bin/windows/contrib/3.6:cannotopenURL'https://cran.rstudio.com/bin/windows/contrib/3.6/PACKAGES'

什么鬼?!

此处省略5000字的辛苦排错的历程描述,直接贴上解决方案:

Rstudio默认使用的国外镜像源,国内无法正常访问。

Rstudio设置如下

Tools>global options>packages

更改镜像源后,重新执行安装操作。
