create_extract: Create subset of common family file variables in long format

In easyPSID: Reading, Formatting, and Organizing the Panel Study of Income Dynamics (PSID)

Description

Creates an extract dataset in long format consisting of the 500 most frequently reoccurring PSID Family Variables across all supplied waves of the PSID.

Usage

create_extract(in_direc, out_direc, num_vars = 500, all_years = F)

Arguments

in_direc	Directory containing waves of the Family Files in .rds format
out_direc	Directory to place export file into
num_vars	Number of variables to include in export dataset (default = 500). High variable counts with many waves of data require a significant amount of RAM, and may cause this function to throw errors if a computer's RAM is insufficient
all_years	Select most common variables based on all years of the PSID rather than based in the data actually supplied

Examples

create_extract(
    in_direc=system.file("extdata","rds_dir", package = "easyPSID"),
    out_direc=tempdir(),
    num_vars=25,
)
