快速加载R 包

安装包的代码

Biocounductor 包

biopackage<-c("A","B") 
for (pkg in biopackage){
  if (! require(pkg,character.only=T) ) {
    BiocManager::install(pkg,ask = F,update = F)
    require(pkg,character.only=T)
  }
}

Cran 包

cranpackage<-c("A","B") # cran 包
for (pkg in cranpackage){
  if (! require(pkg,character.only=T) ) {
    install.packages(pkg,ask = F,update = F)
    require(pkg,character.only=T)
  }
}

查看R包下面都有什么函数：

ls("package:limma") #以 limma 包为例
