Merge different dataset-CodePudding

I have a question, I need to merge two different dataset in one but they have a different class. How I can I do? rbind doesn't work, ideas?

nycounties <- rgdal::readOGR("https://raw.githubusercontent.com/openpolis/geojson-italy/master/geojson/limits_IT_provinces.geojson")

city <- c("Novara", "Milano","Torino","Bari")
dimension <- c("150000", "5000000","30000","460000")
df <- cbind(city, dimension)
 
total <- rbind(nycounties,df)

CodePudding user response：

Are you looking for something like this?

nycounties@data = data.frame(nycounties@data,
                             df[match(nycounties@data[, "prov_name"],
                                      df[, "city"]),])

Output

nycounties@data[!is.na(nycounties@data$dimension),]
