R 语言assign函数用法

assign函数在循环时候，给变量赋值，算是比较方便

举例说明：

1、

for (i in 1:(length(rowSeq)-1)){
  assign(paste("nginx_server_fields7_", i, sep = ""), nginx_server_fields7[(rowSeq[(i-1)+1]):(rowSeq[i+1]), ])
}

for (i in 1:3){
    assign(paste("a", i, sep = ""), i:10)
}

ls()
[1] "a1" "a2" "a3" "i"

> a1
 [1]  1  2  3  4  5  6  7  8  9 10
> a2
[1]  2  3  4  5  6  7  8  9 10
