先在R的控制台中输入这个：
install.packages(c('repr', 'IRdisplay', 'evaluate', 'crayon', 'pbdZMQ', 'devtools', 'uuid', 'digest'))
devtools::install_github('IRkernel/IRkernel')
IRkernel::installspec(user = FALSE)
最后一步可能有问题 参考stackoverflow上的链接：

If Anaconda is installed and the Jupyter-Notebook with it (should be the standard install), open up the Anaconda prompt, not the Windows command prompt or the Anaconda Navigator
Look up the executable of R (not Rgui or Rstudio), it should be somewhere like C:\Program Files\R\R-3.5.1\bin and remember the path typing cd C:\Program Files\R\R-3.5.1\bin and start R by typing R
typing IRkernel::installspec()
Now you can start an R kernel within Jupyter-Notebook
