helper function for package to set metadata attributes of a dataset

Source: R/utils_metadata_add.R
metadata_add.Rd

Together with the metadata_mapping script, this can be used annually to update the metadata for datasets in a package. It just makes it easier to set a few metadata attributes similarly for a number of data elements, for example, to add new or update existing attributes.

Usage

metadata_add(x)

Arguments

x

dataset (or any object) whose metadata (stored as attributes) you want to update or create EJAM, EJScreen, and other dataset versions and release dates are tracked in DESCRIPTION

Value

returns x but with new or altered attributes

Details

This utility would be used in scripts in EJAM/data-raw/ to add metadata to objects like x before use_data(x, overwrite=T)

  x <- data.frame(a=1:10,b=1001:1010)

#> $names
#> [1] "a" "b"
