QUESTION
I'm working with transportation network dataset and I want to import traffic speed data provided as JSON format.
I could read the data in R using read.scorata(). However, I couldn't covert it to a spatial dataframe to be used for further analysis. There is one field in the current dataframe which is encoded polyline. How can I convert using this field?

can decode those polylines into coordinates.
To convert to an sf
object currently requires a couple of steps. (There are plans to make this part of the googlePolylines library)
QUESTION
I have an interactive visualization that connects to a city government's police data API.
When certain combinations of inputs are selected, my API call comes back empty and I get a nasty red error message (as my plot inputs are unavailable).
Can someone tell me how to display a more informative error message along the lines of, "there are no incidents matching your selection, please try again"? I would like this error message to appear as a showNotification and my ggplot not to render.
Below is an extremely stripped down version of what I am doing. Note how when a combination like "AVONDALE" and "CHEMICAL IRRITANT" is selected, the chart renders, whereas when a combination like "ENGLISH WOODS" and "TASER-BEANBAG-PEPPERBALL-40MM FOAM" is selected, an error message is returned. This error message is what I would like to address with a showNotification alert.
Note that this uses the Socrata API, so the package RSocrata must be installed and loaded.
