问题描述
我目前正在处理一个脚本，该脚本应该基于配置"文件来分析数据集.
I'm currently working on a script which should analyze a dataset based on a 'configuration' file.
此文件的输入例如:
configuration.txt:
configuration.txt:
123456, 654321
409,255,265
1
它也可以包含其他值，但是它们都是数字.在上述示例中，应按以下方式读取文件:
It can contain onther values as well, but they will al be numeric. In the example described above the file should be read in as follows:
timestart <- 123456
timeend <- 654321
exclude <- c(409,255,265)
paid <- 1
配置文件的布局不是固定的，但它应包含一个开始时间(unix)，结束时间(unix)一个数组，其中包含要排除的数字和其他字段.最后，它应该由用户在GUI中指定的字段构造.我不知道哪种格式最适合这种情况，但是一旦这些基本知识起作用，我认为这不会成为大问题.
The layout of the configuration file is not fixed, but it should contain a starting time (unix) an ending time (unix) an array with numbers to exclude and other fields. In the end it should be constructed from fields a user specifies in a GUI. I don't know which formatting would suit best for that case, but as soon as I have these basics working I don't think that will be a big problem.
但是，这将使得更难知道哪些值属于哪个变量.
But that will make it harder to know which values belong to which variable.
推荐答案
确实，如Andrie所建议的那样，使用.r配置文件是最简单的方法.我完全忽略了该选项！
Indeed, as Andrie suggested, using a .r config file is the easiest way to do it. I overlooked that option completely!
因此，只需创建一个.r文件，其中已包含变量:
Thus, just make a .r file with the variables already in it:
#file:config.R
timestart <- 123456
timeend <- 654321
exclude <- c(409,255,265)
paid <- 1
在其他脚本中使用:
source("config.R")
瞧.谢谢安德里！
