Re: [R-sig-Geo] Merging Shape files
Within st_join() see the options like "left = TRUE". You may also want to look at st_intersects() Here are other helpful reference websites: https://r-spatial.github.io/sf/reference/geos_binary_pred.html https://cran.r-project.org/web/packages/sf/vignettes/sf3.html -Dexter On Tue, Mar 17, 2020 at 10:29 AM El Mechry El Koudouss < eelkoudo...@fordham.edu> wrote: > 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.

[R-sig-Geo] Merging Shape files
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) -- El Mechry, El Koudouss (Meshry) Graduate Research Assistant Center for International Policy Studies Fordham University Department of Economics Website: www.meshry.com [[alternative HTML version deleted]] ___ R-sig-Geo mailing list R-sig-Geo@r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-geo
