安装
# CRAN
install.packages("package_name")
# bioconductor
if (!requireNamespace("BiocManager", quietly = TRUE))
install.packages("BiocManager")
BiocManager::install("package_names")
# github
library("devtools")
install_github("github_user_name/package_name")
# local
devtools::install_local("path_to_package_file.zip")
升级
update.packages("package_names")
载入
library("package_names") # 如果不存在或缺少相关文件则会报错，程序停止运行
require("package_names") # 如果不存在或缺少相关文件不会报错而是警告，程序继续运行
character.only = TRUE参数可以使得这两个函数可以接受变量所代表的包名：
> a = "ggplot2"
> library(a)
Error in library(a) : there is no package called ‘a’
> library(a, character.only = TRUE)
>
suppressPackageStartupMessages函数使包加载信息不被显示

Title: Create Elegant Data Visualisations Using the Grammar of Graphics
Description: A system for 'declaratively' creating graphics, based on
"The Grammar of Graphics". You provide the data, tell 'ggplot2'
how to map variables to aesthetics, what graphical primitives
to use, and it takes care of the details.
