 Srvyr Setup

 
Srvyr commands are nearly identical to old. The only difference for setup is that you need a variable that uniquely identifies each row in the database (uid).

Because srvyr stores the survey variables locally, the srvyr object takes up much more memory than the dplyr one. However, this object would not grow in size if you added more data variables to your survey, so if your survey is very wide, it will save a lot space.

Analysis

Analysis commands from srvyr are also similar to ones that work on local data.frames. The main differences come from the issues discussed above about explicitly creating variables difficulties in translating R commands, and variable types.

The following analysis is based on the asdfree analysis and shows some basic analysis on the total population, insurance coverage, age and sex.

 Standard evaluation

 
Srvyr now supports the standard evaluation conventions introduced in dplyr version 0.7 and rlang. If you’d like to use a function programmatically, you can use the functions from rlang like rlang::quo() or rlang::sym() to capture the expression and rlang::!! to unquote it. All of these functions are re-exported by srvyr, so you don’t need to load the rlang library to use them.

 
Here’s a quick example, but please see the dplyr vignette vignette("programming", package = "dplyr") for more details.
