od_table_save() creates a tar archive containing all relevant data from the OGD portal. od_table_local() parses the tar archive and recreates the od_table object.

Usage

od_table_save(x, file = NULL)

od_table_local(file)

Arguments

x

an object of class od_table

file

An archive file file for the dataset. For od_table_save(), the default is {id}.tar.gz where id denotes the OGD identifier.

Value

  • for od_table_save(): the path to the generated file

  • for od_table_local(): the OGD identifier

Examples

x <- od_table("OGD_krebs_ext_KREBS_1")

# save dataset as an archive
archive <- file.path(tempdir(), "table.tar.gz")
od_table_save(x, archive)

# read the saved archive
x2 <- od_table_local(archive)

# cleanup
file.remove(archive)
#> [1] TRUE
