R语言中如何批量安装R包

 

1、

> library(qqman)                                                  ## 未安装的包
Error in library(qqman) : 不存在叫‘qqman’这个名字的程辑包
> library(data.table)
Error in library(data.table) : 不存在叫‘data.table’这个名字的程辑包
> library(detectRUNS)
Error in library(detectRUNS) : 不存在叫‘detectRUNS’这个名字的程辑包
> candidate_pak <- c("qqman", "data.table", "detectRUNS")         ## 生成包向量
> candidate_pak            
[1] "qqman"      "data.table" "detectRUNS"
> install.packages(candidate_pak)                                 ## 批量安装包

 

批量加载：

> candidate_pak
[1] "qqman"      "data.table" "detectRUNS"
> for (i in candidate_pak) {                                    ## 利用for循环批量加载
+   library(i, character.only = T)
+ }

 

2、判断包是否提前安装

> candidate_pak <- c("qqman", "data.table", "detectRUNS")
> candidate_pak
[1] "qqman"      "data.table" "detectRUNS"
> candidate_pak %in% installed.packages()
[1] FALSE FALSE  TRUE
> candidate_pak[!candidate_pak %in% installed.packages()]                   ## 过滤已经安装的包
[1] "qqman"      "data.table"
> candidate_pak <- candidate_pak[!candidate_pak %in% installed.packages()]  ## 重新生成候选包向量
> candidate_pak
[1] "qqman"      "data.table"
> install.packages(candidate_pak)                                           ## 批量安装
