nhanes_survey: Apply a function from the survey package to NHANES data

In RNHANES: Facilitates Analysis of CDC NHANES Data

Description

Apply a function from the survey package to NHANES data

Usage

nhanes_survey(survey_fun, nhanes_data, column, comment_column = "",
  weights_column = "", filter = NULL, analyze = "values",
  callback = NULL, ...)

Arguments

survey_fun	the survey package function (e.g. svyquantile or svymean)
nhanes_data	data frame containing NHANES data
column	column name of the variable to compute quantiles for
comment_column	comment column name of the variable
weights_column	name of the weights column
filter	logical expression used to subset the data
analyze	one of "values" or "comments", whether to apply the survey function to the value or comment column.
callback	optional function to execute on each row of the dataframe
...	other arguments to pass to the survey function

Details

This function provides a generic way to apply any function from the survey package to NHANES data. RNHANES provides specific wrappers for computing quantiles (nhanes_quantile) and detection frequencies (nhanes_detection_frequency), and this function provides a general way to use any survey function.

Value

a data frame

Examples

## Not run: 
library(survey)

nhanes_data <- nhanes_load_data("EPH", "2011-2012", demographics = TRUE)

# Compute the mean of triclosan using the svymean function
nhanes_survey(svymean, nhanes_data, "URXTRS", "URDTRSLC", na.rm = TRUE)

# Compute the variance using svyvar
nhanes_survey(svyvar, nhanes_data, "URXTRS", "URDTRSLC", na.rm = TRUE)
