如何在R中获取加载库的安装位置？

library(dplyr)  # 加载dplyr库
library(ggplot2)  # 加载ggplot2库

# 获取加载库的安装位置
lib_paths <- .libPaths()
print(lib_paths)

[1] "/usr/local/lib/R/site-library" "/usr/lib/R/site-library"      
[3] "/usr/lib/R/library"           

library(dplyr)  # 加载dplyr库

# 获取dplyr库的安装位置
dplyr_path <- find.package("dplyr")
print(dplyr_path)

[1] "/usr/local/lib/R/site-library/dplyr"

# 获取所有已安装包的信息
all_packages <- installed.packages()

# 获取dplyr库的安装位置
dplyr_info <- all_packages[all_packages[,"Package"] == "dplyr", ]
dplyr_path <- dplyr_info[,"LibPath"]
print(dplyr_path)

[1] "/usr/local/lib/R/site-library"
