Test Field Names for Invalid Characters

test_valid_fieldnames() checks for field names (e.g data column names) in the metadata that contain invalid special characters. Only underscores and alphanumeric characters are permitted, and names must begin with a letter. If invalid column names exist, the test will fail with a warning, otherwise the test passes.

Usage

test_valid_fieldnames(metadata = load_metadata(here::here()))

Arguments

metadata

The metadata object returned by load_metadata. If parameter not provided, defaults to calling load_metadata in current project directory.

Value

Invisibly returns metadata.

Details

You should run test_fields_match() before you run this function, since this function only checks the field names in the metadata.

Examples

meta <- load_metadata(DPchecker_example("BICY_veg"))
#> Data are provided for example use only. Do not assume that they are complete, accurate, or up to date.
test_valid_fieldnames(meta)
#> ✔ Field names begin with a letter and do not contain spaces or special
#>   characters.
