R环境和包操作相关命令
查询用户HOME地址
Sys.getenv("HOME")
查询R HOME安装地址
Sys.getenv("R_HOME")
查看包的安装目录\设置包的安装目录
.libPaths() \ .libPaths(\'path\')
查看已经安装的包目录
library()
载入mypackage包\删除载入的包
library(mypackage)
require(dplyr)
detach(dplyr)
包的载入library()或require()，安装完包后，需要加载才能使用其中的函数，此时括号中不使用引号。两者的不同之处在于library()载入之后不返回任何信息，而require()载入后则会返回TRUE，因此require()适合用于程序的书写。例如：
library(ggplto2)
> require(foreign)
Loading required package: foreign
> is.logical(require(foreign))
[1] TRUE
卸载包detach()，这是library()的反向操作，此操作主要是为了避免某些包中的函数名称相同，造成冲突，注意与library()的参数不同，detach()参数为detach(package:包的名称),library(包的名称)。例如：
> library(ggplot2) # 加载包
> (.packages()) # 列出当前已经加载的包
[1] "ggplot2" "stats" "graphics" "grDevices" "utils" "datasets" "methods" "base"
> detach(package:ggplot2) # 卸载ggplot2包
> (.packages()) # 列出当前已经加载的包
[1] "stats" "graphics" "grDevices" "utils" "datasets" "methods" "base"
查看启动R时自动载入的包
getOption("defaultPackages")
查看当前载入的包
search()
查看R中载入的包
sessionInfo()
查看已安装包信息
installed.packages()
查看当前已经加载过的R包：
(.packages())
查看全部安装的R包：
.packages(all.available=TRUE)
.packages(all.available=T)
查看某个R包是否已经安装：
library("XML")
查看某个安装的R包：
help(package="XML")
卸载package | 如何卸载已安装的packages
remove.packages("mypackage")
remove.packages(c("pkg1","pkg2"),lib = file.path("path","to","library"))
查看R及其package的version
# R version: version
R.version
# R package version:
library(help=\'XML\')
packageVersion(\'XML\')
升级R，不重装packages
拷贝原library目录下文件到新library目录下
更新包 | 可以定期执行以下
update.packages()
查看"mypackage"的帮助
help(package = \'mypackage\')
查看已经安装包的详细HTML文档
help.start()
查看function（先载入包）
# 查看函数的参数
args(function)
# 自动运行该函数帮助文档中的例子
example(function)
查询包内信息（先载入包）
# 查看某个“函数”或者“方法”的详细内容
?function/method
# 查看"mypackage"中的所有对象
ls("package:mypackage")
查看某个S3泛型函数中所有的方法或者一个类中所有的方法（S3：S version 3）
methods()
查看S4类的方法
showMethods(class = "myClass")
WIN环境下设置环境变量R_LIBS将R包安装到自定义路径
R离线下载R包和依赖
在离线状态下，为了更方便安装R包，可以用以下方式：
# 下载包和依赖到本地目录下
# download
getPackages <- function(packs){
packages <- unlist(
tools::package_dependencies(packs, available.packages(),which=c("Depends", "Imports"), recursive=TRUE)
)
packages <- union(packs, packages)
packages
}
myPackages <- c("dplyr","sqldf","DBI","rJava","RJDBC","forecast","lubridate","xgboost","ggplot2","plyr")
packages <- getPackages(myPackages)
download.packages(packages, destdir="D:/Rpackages/", type="source")
# 把包和依赖传入离线环境后，离线安装：
# install
library(tools)
path <- "D:/Rpackages"
write_PACKAGES(path,type="source")
myPackages <- c("dplyr","sqldf","DBI","rJava","RJDBC","forecast","lubridate","xgboost","ggplot2","plyr")
install.packages(myPackages, contriburl=paste("file:",path,sep=\'\'),type="source")
R常用软件包安装
# 1.在R的控制台,输入
install.packages("servr") # 安装 servr
install.packages("servr", contriburl="http://www.your.url", dependencies = TRUE) # 安装 servr
# 2.若要指定安装目录 (e.g. “mydir”)，则输入
install.packages("stepNorm", contriburl="http://www.biostat.ucsf.edu/jean/software", lib="mydir")
install.packages(\'servr\') # stable version; use a CRAN mirror, or
install.packages(\'servr\', repos=\'http://yihui.name/xran\') # devel version
# 3.在Github上直接安装R包步骤
一、安装devtools包
install.packages("devtools")
library(devtools)
二、安装github上的R包
devtools::install_github(\'lchiffon/REmap\')
library(REmap)
