R語言基礎配置1

設定工作目錄

臨時改變

Session -> Set Working Directory -> Choose Directory

改變預設位置

Tools –> Global options –> General

setwd("D:/sch/RWorkSpace")

這裡還可以選擇R語言的版本，以後更新後應該只在這裡改就ok了。這裡預設直接選擇和電腦作業系統適配，64位，不是我手動配置的欸。

R包的安裝

下了ggplot2的包，控制檯的資訊：

由此看來安裝新的包也只是從開源的網站上下載一些zip檔案然後解壓到library目錄中，並未做多餘的事，知道這一點之後，我們今後可以手動安裝包，手動調整，更新

Rtools

定義

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:

Note for RStudio users: please check you are using a recent version of RStudio (at least 1.2.5042

) to work with rtools40.

這麼看來 x86是64位，i686是32位，對應？

之前下載R語言的時候64位和32位的都下載了。

還需要配置一下環境變數

我們發現rtools_home的系統變數已經自動添加了。

接下來是path，按照官方文件的配置即可。

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

我們看到jsonlite包已經躺在了我們期待的目錄下，表明上述操作成功。

最後一行顯示

The downloaded source packages are in
	‘C:\Users\ChangHao\AppData\Local\Temp\Rtmp6p9J0w\downloaded_packages’

似乎把一些東西存入了C盤？沒有關係，這是temp檔案，appdata，而且不是很大，其實就是jsonlite_1.7.2.tar.gz，大小412K.
