# R: Working with GeoJSON data and resolve 'Error in ogrInfo'

This blog presents how to work with GeoJSON data in R, and proposes the solution of "Error in ogrInfo(dsn = dsn, layer = layer, encoding = encoding, use_iconv = use_iconv"

Since working in franprix, I’ve accomplished many projects, for different departments. Thanks to this opportunity, I understood business of various services and learnt lots of technique of R. Today I’d like to share with you how to read GeoJSON data in R.

Concerning the dataset, we take the Paris international tourist area as an example. Then we use either rgdal or geojsonio package, and read it as following.

Moreover, for reading GeoJSON data, many web sites recommend similar codes but without require_geomType parameter, and many people get following errors:

Thanks to stackoverflow, I understood what the error means, and extract the features that I need.

After confirming with codes above, I could make sure that wkbPolygon is the parameter needed, so it was added in the codes at the beginning.

This method can be also applied with the result of leaflet(). We can plot some places in the map with leaflet(), then use addPolygons() to add the ploygons-layer.
