设置工作目录
临时改变
Session -> Set Working Directory -> Choose Directory
改变默认位置
Tools –> Global options –> General
setwd("D:/sch/RWorkSpace")
这里还可以选择R语言的版本，以后更新后应该只在这里改就ok了。这里默认直接选择和电脑操作系统适配，64位，不是我手动配置的欸。

由此看来安装新的包也只是从开源的网站上下载一些zip文件然后解压到library目录中，并未做多余的事，知道这一点之后，我们今后可以手动安装包，手动调整，更新
Rtools
定义
https://cran.rstudio.com/bin/windows/Rtools/
Note that rtools40 is only needed build R packages with C/C++/Fortran code from source. By default, R for Windows installs the precompiled “binary packages” from CRAN, for which you do not need rtools!
To use rtools40, download the installer from CRAN:
- On Windows 64-bit: rtools40v2-x86_64.exe (recommended: includes i386, x64, and x64-ucrt compilers)
- On Windows 32-bit: rtools40-i686.exe (i386 compilers only)
Note for RStudio users: please check you are using a recent version of RStudio (at least 1.2.5042) to work with rtools40.
这么看来 x86是64位，i686是32位，对应？
之前下载R语言的时候64位和32位的都下载了。
还需要配置一下环境变量
我们发现rtools_home的系统变量已经自动添加了。
接下来是path，按照官方文档的配置即可。
Putting Rtools on the PATH
After installation is complete, you need to perform one more step to be able to compile R packages: you need to put the location of the Rtools make utilities (bash, make, etc) on the PATH. The easiest way to do so is create a text file .Renviron in your Documents folder which contains the following line:
PATH="${RTOOLS40_HOME}\usr\bin;${PATH}"
You can do this with a text editor, or from R like so (note that in R code you need to escape backslashes):
writeLines('PATH="${RTOOLS40_HOME}\\usr\\bin;${PATH}"', con = "~/.Renviron")
Now restart R, and verify that make can be found, which should show the path to your Rtools installation.
Sys.which("make")
## "C:\\rtools40\\usr\\bin\\make.exe"
If this works, you can try to install an R package from source:
install.packages("jsonlite", type = "source")
If this succeeds, you’re good to go! See the links below to learn more about rtools40 and the Windows build infrastructure.
> install.packages("jsonlite", type = "source")

The downloaded source packages are in

我们看到jsonlite包已经躺在了我们期待的目录下，表明上述操作成功。
最后一行显示
The downloaded source packages are in
‘C:\Users\ChangHao\AppData\Local\Temp\Rtmp6p9J0w\downloaded_packages’
似乎把一些东西存入了C盘？没有关系，这是temp文件，appdata，而且不是很大，其实就是jsonlite_1.7.2.tar.gz，大小412K.
再装一次ggplot2
> install.packages("ggplot2")
