This function wraps the "free" pdok service, and allows for free search.
For syntax and examples see the documentation of pdok.
A more easy/convenient but simpler function for geocoding is
nl_geocode.
nl_free(q, rows = NULL, start = NULL, fq = NULL, lat = NULL, lon = NULL, type = NULL, fl = NULL, df = NULL, ..., verbose = FALSE)
| q | query to geocoding service. |
|---|---|
| rows | maximum number of rows to be returned. Default is 10. |
| start | start index.Default is 0. |
| fq | apply a filter to the query, e.g. fq=bron:BAG. The default filter is 'type:(municipality OR town OR neiborhood OR road OR postcode OR adress)'. Use fq=* to remove the default filter. |
| lat | enter a decimal degree (latitude, in WGS84). Together with lon this will define a point to search from. Search results will be ordered by distance from this point. For example: 'lat=52.09&lon=5.12' |
| lon | enter a decimal degree (longitude, in WGS84). Together with lat this will define point to search from. Search results will be ordered by distance from this point. For example: 'lat=52.09&lon=5.12' |
| type | restrict the results on a specific type. |
| fl | fields to return. |
| df | field that should be search in. |
| ... | parameters passed to the pdok webservice |
| verbose |
|
The result of the pdok free webservice converted to a R list object.
