Add `subset()` style function

[smishr]

In R, there is a subset function which is a transformation from SurveyDesign->SurveyDesign and ReplicateDesign->ReplicateDesign such that the domain of the survey is restricted to given condition (eg age>18 or sex="Male"). Subpopulation estimates are then calculated with any API function like mean total etc (instead of the full population estimate)

How to implement this? for replicate design R code is given line 667 here, for SurveyDesign given line 314 here

It's simple to add for replicate design, it's just a subset from DataFrames.

I would like to work on this issue

Hi @EngPeterAtef Sorry, I am not sure why I didn't get a notification when you commented. Apologies for the delay.

@EngPeterAtef

We want to implement this function in Julia: https://r-survey.r-forge.r-project.org/survey/html/subset.survey.design.html
