# NCHS data: public use files (PUFs) from the National Center for Health Statistics (NCHS) Selected public use files (PUFs) from the National Center for Health Statistics (NCHS). These complex surveys can be analyzed using the `survey` or the `surveytable` packages. ## Installation You can install `nchsdata` like so: ``` r install.packages(c("remotes", "git2r")) remotes::install_github("CDCgov/nchsdata", upgrade = "never") ``` ## Documentation Find the documentation for `nchsdata` here: ## Example The data systems currently available in `nchsdata` are: #> ed2020 National Hospital Ambulatory Medical Care #> Survey (NHAMCS) Emergency Department (ED) 2020 #> Public Use File (PUF) #> namcs2019 National Ambulatory Medical Care Survey (NAMCS) #> 2019 Public Use File (PUF) #> nhanes2016s National Health and Nutrition Examination #> Survey (NHANES) 2013-2016 Public Use File (PUF) #> (select variables and observations) #> 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: ``` r library(nchsdata) library(surveytable) ``` ``` r 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 ``` ``` r tab("hbp", drop_na = TRUE) ```
