On LinkedIn, Juan Pablo Ferreira shared this new R package he's working on. It brings a tidy style approach to survey weight adjustment. It's pipeable and the API is like tidymodels. I'll be checking it out! jpferreira33.github.io/weightflow/

I love R for everything statistics, but I've always been a little jealous of statisticians using SPSS Complex Samples or SAS SURVEYSELECT to design their samples. So I decided to build samplyr, a tidy and pipe-friendly grammar for survey sampling design in #rstats. dickoa.gitlab.io/samplyr/inde...
