使用本地宏将具有公共前缀的多个变量制成表格 [英] Tabulate multiple variables with common prefix using a local macro

问题描述

我有许多变量的名称以前缀indoor开头. indoor之后的内容不是数字的(这会使一切变得更简单).

I have a number of variables whose name begins with the prefix indoor. What comes after indoor is not numeric (that would make everything simpler).

我想为这些变量中的每一个列表.

I would like a tabulation for each of these variables.

我的代码如下:

local indoor indoor*  
foreach i of local indoor {  
    tab `i' group, col freq exact chi2  
}

问题是foreach命令中的indoor解析为indoor*，而不是我希望的indoor问题列表.因此，tab命令后跟的变量太多(它只能处理两个)，这会导致错误.

The problem is that indoor in the foreach command resolves to indoor* and not to the list of the indoor questions, as I hoped. For this reason, the tab command is followed by too many variables (it can only handle two) and this results in an error.

简单的解决方法是将第一个命令替换为:

The simple fix is to substitute the first command with:

local indoor <full list of indoor questions>

但这是我要避免的事情，那就是必须找到这些变量的所有名称，然后将它们粘贴到代码中.看来有一个更快的解决方法，但是我想不到任何解决方法.

But this is what I would like to avoid, that is to have to find all the names for these variables and then paste them in the code. It seems there is a quicker fix for this but I can't think of any.

推荐答案

您可以使用

foreach i of var `indoor' {
   tab `i' group, col freq exact chi2
}
