Read filetype from a zipped folder based on the file ending

read_zipdata(zfile, pattern = ".dta$", readfn = haven::read_dta, ...)

Arguments

zfile: Path to `.zip` file containing flat file dataset, usually ending in filename `XXXXXXFL.zip`
pattern: String detailing which filetype is to be read from within the zip by means of a grep. Default = ".dta$"
readfn: Function object to be used for reading in the identified file within the zip. Default = `haven::read_dta`
...: additional arguments to readfn

Examples

if (FALSE) { # \dontrun{
# get the model datasets included in the package
model_datasets <- model_datasets

# download just the zip
g <- get_datasets(
dataset_filenames = model_datasets$FileName[1],
download_option = "zip"
)

# and then read from the zip. This function is used internally by rdhs
# when using `get_datasets` with `download_option = .rds` (default)
r <- read_zipdata(
g[[1]], pattern = ".dta"
)

# and we can pass a function to read the file and any other args with ...
r <- read_zipdata(
g[[1]], pattern = ".dta", readfn = haven::read_dta, encoding = "UTF-8"
)
} # }
