Rstudio中安装package出现的问题及解决
Rstudio中安装package问题
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：
# set a CRAN mirror
local({r <- getOption(“repos”)
r[“CRAN”] <- “mirrors.tuna.tsinghua.edu/CRAN/”
options(repos=r)}
⼆、⼿动安装package
1.在R studio下，选择packages
2.选择Install
3.Install from栏选择Package Archive File(.zip;.)
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: Rtools is required to build R packages but is not currently installed. Please download and install the appropriate version of Rtools before proceeding: cran.rstudio/bin/windows/Rtools/
Installing package into ‘C:/Users/likailei/Documents/R/win-library/3.6'
(as ‘lib' is unspecified)
Warning in install.packages :

Warning in install.packages :

Warning in install.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。
install.packages("mirt")
