R语言中批量加载包

 

方法1：

> (.packages())                                                          ## 查看已安装的包
[1] "stats"     "graphics"  "grDevices" "utils"     "datasets"  "methods"  
[7] "base"     
> candidate_pak <- c("qqman", "data.table", "detectRUNS")
> for (i in candidate_pak) {                                              ## 利用for循环批量加载
+   library(i, character.only = T)
+ }
> (.packages())
 [1] "detectRUNS" "data.table" "qqman"      "stats"      "graphics"  
 [6] "grDevices"  "utils"      "datasets"   "methods"    "base"

[7] "base"     
> candidate_pak <- c("qqman", "data.table", "detectRUNS")                   ## 候选包
> lapply(candidate_pak, function(x){library(x, character.only = T)})        ## 利用lapply函数批量加载
> (.packages())                                                             ## 查看已经安装的包
