easyPSID (version 0.1.2)

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

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

# NOT RUN {
create_extract(
    in_direc=system.file("extdata","rds_dir", package = "easyPSID"),
    out_direc=tempdir(),
    num_vars=25,
)
# }
