Examples

# \donttest{
dp <- ct_dp_example()
ct_dp_filter(package = dp, table = "observation",
scientificName == "Vulpes vulpes", observationLevel == "event"
)

#> • deployments: 4 rows
#> • media: 10 rows
#> • observations: 1 rows
#> 
#> And 1 additional resource:
#> • individuals
#> Use `unclass()` to print the Data Package as a list.
