nhanes_design: Generate NHANES design object

In outcomesinsights/nhanes.tools: Easily Download and Combine NHANES Files for Analysis

Description

Takes a data.frame with NHANES data and at least one weight variable, and creates the proper design object for it. It simply puts the proper PSU strata, nest, and user-supplied weight into the svydesign function. Note this does NOT set options(survey.lonely.psu = "adjust").

Usage

nhanes_design(df, wt = "WTINT2YR")

Arguments

df	a data.frame or data.table created from NHANES data
wt	The weight variable in the data as a character vector. Common options include WTINT2YR, WTMEC2YR, and WTSA2YR. See NHANES documentation for assigning weights across multiple years, and for choosing weights when there is more than 1 sampling frame (e.g., interview, mobile exam, fasting laboratory values, and other data subsets)

Value

Returns a survey design object (which contains all of the data) for use in analyses

Examples

## Not run:
