从3.4.1 升级到最新
懒得去官网下载
在R studio 执行一下代码
install.packages("installr")
library(installr)
updateR()
但是执行出是
> install.packages("installr")
also installing the dependencies ‘glue’, ‘magrittr’, ‘stringi’, ‘stringr’
There are binary versions available but the source versions are later:
binary source needs_compilation
glue 1.2.0 1.3.0 TRUE
stringi 1.1.7 1.2.3 TRUE
Binaries will be installed

总之就是失败了。
最后这个更新语句，我在R 里尝试执行。

我没想通。
后来点击了界面：
显示
没想明白。
后续：
我不开心了。
重新在R装了一下。之前的一切都是徒劳。
