Load selected NHANES files for a specific year
1 | load_nhanes(f = "", yr, data_dir = "./data", lab = FALSE)
|
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) |
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
