法學如何在 Windows 作業系統中查詢在 R 中安裝的包的位置？
要在 Windows 作業系統中查詢在 R 中安裝的包的位置，我們可以使用下面提到的命令 −
.libPaths()
這將在第一行返回已安裝包的位置，在第二行返回程式檔案的位置。
使用下面提到的程式碼在 Windows 作業系統中查詢已安裝包的位置 −
.libPaths()
輸出
如果你執行給定的程式碼段，它會生成以下輸出 −
[1] "C:/Users/Nizam/Documents/R/win-library/4.0" [2] "C:/Program Files/R/R-4.0.4/library"
使用下面提到的程式碼在 Windows 作業系統中查詢已安裝包的位置 −
installed.packages()[1:20,]
輸出
如果你將上面給定的所有程式碼段作為單個程式執行，它會生成以下輸出 −
