Anaconda安装R语言及虚拟环境下如何添加R和python到jupyter
有时候，会简单调用R语言，anaconda加装R语言。
#20220323更新
conda install r
#命令行输入R，进行R环境
install.packages('IRkernel')
IRkernel::installspec()
#刷新jupyterlab即可看到R。
#20220408更新
区别于上次的操作，再次添加不同的虚拟环境下的R，执行如下：
conda create -n r413
conda install -c conda-forge r-base
install.packages('IRkernel')
IRkernel::installspec(name = 'ir413', displayname = 'R 4.1.3')
# 上面这步会报错，是因为，虚拟环境r413下，直接输入R进入的R环境，并没有指定对应的r版本，此时，我们应该进入虚拟环境后，以输入r的具体路径，替代输入R
conda activate r413
whereis R
[1] R: /usr/bin/R /usr/lib/R /etc/R /usr/local/lib/R /usr/share/R /root/anaconda3/envs/r413/bin/R /usr/share/man/man1/R.1.gz
# 此时，可以看出，此处返回的R路径为/root/anaconda3/envs/r413/bin/R，我们实际需要运行的具体路径为/root/anaconda3/envs/r413/lib/R/bin
# 我们同样可以借助print(system.file("kernelspec", package = "IRkernel"))指令，去查看IRkernel的安装路径
print(system.file("kernelspec", package = "IRkernel"))
[1] "/root/anaconda3/envs/r413/lib/R/library/IRkernel/kernelspec"
.libPaths()
[1] '/root/anaconda3/envs/r413/lib/R/library'
R.home()
[1] '/root/anaconda3/envs/r413/lib/R'
/root/anaconda3/envs/r413/lib/R/bin/R #进入指定路径的R
IRkernel::installspec(name = 'ir413', displayname = 'R 4.1.3')
# 成功
# 补充python添加虚拟环境到jupyter
conda create -n py310 python=3.10.4 ipykernel
conda activate py310
python -m ipykernel install --user --name py310 --display-name "Python 3.10.4"
# 成功
# 查看jupyter已有内核
jupyter kernelspec list
# 删除jupyter已有内核
jupyter kernelspec uninstall ir413conda install R
conda update r r=3.5.2 #指定版本安装
---
#R环境或RStudio中，输入命令：
install.packages(c('repr', 'IRdisplay', 'evaluate', 'crayon', 'pbdZMQ', 'devtools', 'uuid', 'digest'))
devtools::install_github('IRkernel/IRkernel')
# 只在当前用户下安装
IRkernel::installspec()
# 或者是在系统下安装
IRkernel::installspec(user = FALSE)
conda install -c r r-essentials #或者直接在conda中安装即可
