Subsetting the neighborhoods

You don't need all those extraneous neighborhoods in New York, so you'll subset out just the neighborhoods in New York County. You already know how!

neighborhoods is a SpatialPolygonsDataFrame and you learned back in Chapter 2 how to subset based on the column in the data slot. The key was creating a logical vector, then subsetting the SpatialPolygonsDataFrame like a data frame.

How can you identify the right neighborhoods? Check out:

head(neighborhoods@data)

The CountyFIPS is a numeric code that identifies the county. If you can figure out the code for New York County, you can keep just the rows with that value.

The nyc_tracts_merge object also has country codes in the column COUNTYFP. Find the unique() values to find the code for New York County.
Subset neighborhoods by adding a logical that tests if neighborhoods$CountyFIPS has the right value.
Edit your plot to use manhat_hoods instead of neighborhoods.
Add a tm_text() layer, mapping text to "NTAName".
