load_nhanes: Load selected NHANES files for a specific year

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

Description

Load selected NHANES files for a specific year

Usage

load_nhanes(f = "", yr, data_dir = "./data", lab = FALSE)

Arguments

f	= nhanes file (no suffix – just main file code like "mcq" and not "mcq_f" or "mcq_f.rds")
yr	= first year of wave,
data_dir	= The directory in which all of your NHANES subdirectories (one for each year) reside. Default is the project "data" subdirectory (i.e., "./data") but if your data are elsewhere, you must specify the directory. Keep in mind that this will be a directory that contains all of your NHANES subdirectories. It is NOT the subdirectory for a specific year. Do not use a slash (/) at the end.
lab	= indicator of whether the label file should be included (if FALSE, then data file will be retrieved)

Value

Returns a dataframe (a data.table) with the requested file. This function can be used as a stand-alone function to get a single file, or it can be used with the load_merge function to do multiple files

Examples

## Not run: 
Load single data files
demographics <- load_nhanes("demo", 2003)
med_cond_ques <- load_nhanes("mcq", 2009)

# Load single label files
demographics_labels <- load_nhanes("demo", 2003, lab = TRUE)
med_cond_ques_labels <- load_nhanes("mcq", 2009, lab = TRUE)

## End(Not run)
