windows下jupyter notebook配置IRkernel见：
玩转Jupyter Notebook5-配置python|R|Julia|Stata
前提是R已经安装完毕
第一步
在R中完成
options(repos=structure(c(CRAN="https://mirrors.tuna.tsinghua.edu.cn/CRAN/")))
install.packages('IRkernel',dependencies=TRUE)报错：
tar: Failed to set default locale
解决：
system('defaults write org.R-project.R force.LANG en_US.UTF-8')
参考：https://stackmirror.com/page/3xysh3tfepl
第二步
R中完成
IRkernel::installspec(user = FALSE)报错：
Error in IRkernel::installspec(user = FALSE) :
jupyter-client has to be installed but “jupyter kernelspec --version” exited with code 127.
In addition: Warning message:
In system2("jupyter", c("kernelspec", "--version"), FALSE, FALSE) :
error in running command
解决：
R中完成
R.home()/Library/Frameworks/R.framework/Resources/
添加bin/R
终端完成
>/Library/Frameworks/R.framework/Resources/bin/R
IRkernel::installspec(user = FALSE)#To install system-wide, set user to False in the installspec command:报错：
[Errno 13] Permission denied: '/usr/local/share/jupyter'
Perhaps you want to install with `sudo` or `--user`?
解决：
直接root安装，完美解决
终端完成
>sudo /Library/Frameworks/R.framework/Resources/bin/R
R中完成
options(repos=structure(c(CRAN="https://mirrors.tuna.tsinghua.edu.cn/CRAN/")))#设置镜像源
install.packages('IRkernel',dependencies=TRUE)试开URL’https://mirrors.tuna.tsinghua.edu.cn/CRAN/bin/macosx/contrib/4.0/IRkernel_1.1.1.tgz'

下载的二进制程序包在/tmp/RtmpAqkmDv/downloaded_packages里
IRkernel::installspec(user = FALSE)#To install system-wide, set user to False in the installspec command:[InstallKernelSpec] Installed kernelspec ir in /usr/local/share/jupyter/kernels/ir
退出R，jupyter notebook一下
完美解决。
jupyter notebook使用R实例
library(RColorBrewer) # 用分类调色板
par(mfrow = c(2, 1), mar = c(3, 2.5, 0.5, 0.1))
death <- t(VADeaths)[, 5:1]
barplot(death, col = brewer.pal(4, "Set1"))
barplot(death,
col = brewer.pal(4, "Set1"), beside = TRUE,
legend.text = TRUE
)
