st_as_sf fails when the api returns a list

[steffengreup]

On some occasions, the API returns a list instead of a data.frame. This seems to happen when no match is found.

For example:

pdok_res <- nlgeocoder::nl_free("1013AB", rows = 1)

str(pdok_res)
#> List of 1
#>  $ response:List of 4
#>   ..$ numFound: int 0
#>   ..$ start   : int 0
#>   ..$ maxScore: num 0
#>   ..$ docs    : list()

This causes sf to throw an error when using the nl_geocode function with both the (default) output format wsg84 and output format rd:

nlgeocoder::nl_geocode("1013AB")
#> Error in UseMethod("st_as_sf"): no applicable method for 'st_as_sf' applied to an object of class "list"

Hi Steffen,

Thanks for reporting! This issue has been fixed in the current github version, which should be put on CRAN.
For the time being you can use:

remotes::install_github("uRosConf/nlgeocoder")

Best,

Edwin

Will close when on CRAN
