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
