remotes::install_github("CDCgov/nchsdata", upgrade = "never")

Documentation

Find the documentation for nchsdata here: https://cdcgov.github.io/nchsdata

Example

The data systems currently available in nchsdata are:

#>                         Survey (NHAMCS) Emergency Department (ED) 2020
#>                         Public Use File (PUF)
#> namcs2019               National Ambulatory Medical Care Survey (NAMCS)
#>                         2019 Public Use File (PUF)

#> rcc2018                 National Study of Long-Term Care Providers
#>                         (NSLTCP) Residential Care Community (RCC) 2018
#>                         Public Use File (PUF)
#> rccsu2018               National Study of Long-Term Care Providers
#>                         (NSLTCP) Residential Care Community (RCC)
#>                         Services User (SU) 2018 Public Use File (PUF)

If you have surveytable, you can use it to analyze these surveys. For example:

set_survey("rccsu2018")
#>                        _              
#> Survey name            RCC SU 2018 PUF
#> Number of variables    81             
#> Number of observations 904            
#> Stratified Independent Sampling design
#> svydesign(ids = ~1, strata = ~pufstrata2 + su_facid, fpc = ~pufpopfac2, 
#>     weights = ~suwt, data = d1)
#> * To adjust how counts are rounded, see ?set_count_int
