如何将列表保存到文件并再次读入(在R中)? [英] How can i save a list to a file and read it in again (in R)?

问题描述

我已经用R中的poLCA软件包估算了一个模型，并希望将起始值保存到文件中，因此我可以随时重新估算完全相同的模型.

I´ve estimated a model with the poLCA-package in R and want to save the starting values to a file, so i can re-estimate exactly the same model anytime.

这是一个模型的起始值的列表:

This is a list of starting values for one model:

List of 8
 $ : num [1:2, 1:6] 0.219 0.193 0.16 0.193 0.184 ...
 $ : num [1:2, 1:6] 0.0731 0.2054 0.228 0.144 0.2028 ...
 $ : num [1:2, 1:6] 0.0396 0.0965 0.0286 0.1494 0.1609 ...
 $ : num [1:2, 1:6] 0.20998 0.173634 0.105792 0.000588 0.06236 ...
 $ : num [1:2, 1:6] 0.163 0.19 0.167 0.178 0.246 ...
 $ : num [1:2, 1:6] 0.1602 0.1438 0.1963 0.0848 0.2218 ...
 $ : num [1:2, 1:6] 0.0298 0.3022 0.2179 0.094 0.0228 ...
 $ : num [1:2, 1:6] 0.0167 0.2444 0.3257 0.1298 0.3652 ...

这些都是它的值:

首先我想，我可以将列表转换为数据框并将其另存为.csv文件.但是我不知道如何读取该文件以具有与我从模型中获得的列表完全相同的列表. 我已经看过stackoverflow了，但是没有找到我问题的答案.我不介意文件是.csv，.txt还是一个文件或多个文件.很抱歉，如果我不能为我的问题提供更多的想法或代码.我不知道从哪里开始. 谢谢您的帮助！

First i thought, that i can convert the list to a dataframe and save it as a .csv-file. But i don´t know, how i would read-in this file to have exactly the same list, that i get from the model. I already looked around stackoverflow, but didn´t find the answer to my question. I don´t mind if the file would be .csv, .txt or if it´s one file or many. I´m sorry, if i can´t offer any more ideas or code for my question. I don´t know where to start. Thank you for your help!

推荐答案

save(starting.values, file="fname.RData")
?save

允许您将一个或多个R对象保存到单个文件中.

Allows you to save one or more R objects to a single file.

加载

load("fname.RData")
