[R-sig-Geo] Merging Shape files

[El Mechry El Koudouss]

Dear readers,
I downloaded a shapefile with data on crime incidents in Washington DC in
2016 (available here:
https://opendata.dc.gov/datasets/crime-incidents-in-2016) and another
shapefile with data on parks and recreation areas, also in Washington DC
(available here: https://opendata.dc.gov/datasets/parks-and-recreation-areas).
I was able to read both shapefiles using st_read() from the sf package. My
question is, how can I merge the two data sets? I tried st_join() but it
simply resulted in empty columns from the parks dataset getting added to
the crime data. Any guidance would be much appreciated.
library(sf)
parks <- st_read("Parks_and_Recreation_Areas.shp")
crime <- st_read("Crime_Incidents_in_2016.shp")
df <- st_join(crime, parks)
