希望这是一个简单的解决方案的简单问题。我有几个国家收集的加权调查数据。我正在尝试创建一个表格，按国家/地区显示具有相应CI和SE的特定调查问题的比例响应。在＆＃34;调查中使用svyby＆＃34;对于第一个问题，包似乎工作正常，每个国家/地区的每个因素级别至少有一个响应。
svyby(~V34c,~V4, design = data, svymean, na.rm=T,vartype=c("ci","se"))
以一般形式产生预期输出：
[国家，既不同意也不反对，V34cNo数据，V34cOverall同意，......]
AU-Australia，0.31459269,0.0425825851,0.2935771 ......
BE-Belgium，0.31884528,0.0895231917,0.2024003 ......
BG-Bulgaria，0.29237157,0.0649909093,0.4632688 ...... ...
然而，当在一些因子水平为空的问题上运行相同的代码时（例如，在＃34;没有观察到整体同意＆＃34;在保加利亚），我得到了时髦的输出：
svyby(~V34c,~V4, design = data, svymean, na.rm=T,vartype=c("ci","se"))

当我从数据集中删除违规国家时，代码似乎按照我预期的方式工作，但我希望还有其他解决方案。
谢谢！
