用lm对象填充列表 [英] Populating a list with lm objects

问题描述

我正在尝试使用R中OLS的结果填充命名列表.

I am trying to populate a named list with the results of an OLS in R. I tried

li = list()
for (i in 1:10)
    li[["RunOne"]][i] = lm(y~x)

此处RunOne是一个随机名称，用于指定拟合运行一次，y和x是一些预定义的向量.这会中断并给我错误

Here RunOne is a random name that designates the fitting run one, y and x are some predefined vectors. This breaks and gives me the error

Warning message:
In l[["RunOne"]][1] = lm(y ~ x) :
  number of items to replace is not a multiple of replacement length

尽管我了解该错误，但是我不知道如何解决.

Though I understand the error, but I don't know how to fix it.

推荐答案

有两种解决方案(具体取决于您要执行的操作).

There are two solutions (depending on exactly what you want to do).

1. 创建一个列表，并将lm对象添加到每个元素:

1. Create a list, and add an lm object to each element:

li = list() 
for (i in 1:10) 
    li[[i]] = lm(y~x)

具有列表列表:

Have a list of lists:

li[["RunOne"]] = list()
for (i in 1:10) 
    li[["RunOne"]][[i]] = lm(y~x)

通常，单括号[ ]用于矢量和数据帧，双括号用于列表.

Typically, single brackets [ ] are used for vectors and data frames, double brackets are used for lists.
