sf object for New York leukemia data.
Description
The number of incident leukemia cases from
1978-1982 per census tract for an 8-county region of
upstate New York.
This is the same data as in nydf in a different
format.
Note that the coordinates in the polygons have been
projected to a different coordinate system (UTM, zone
18) compared to nydf, but the order of the
regions/polygons is the same as in nydf.
Usage
data(nysf)
Format
A sf with 281 rows and 18 columns:
- areaname
The name of the region.
- areakey
Census tract id.
- xorig
x-coordinate associated with the centroid of each region on the ORIGINAL scale.
- yirug
y-coordinate associated with the centroid of each region on the ORIGINAL scale.
- pop8
The population (1980 census) of the region.
- tractcas
The number of leukemia cases between 1978-1982, rounded to two decimal places.
- propcas
The proportion of cases relative to population.
- pctownhome
The percentage of homeowners in the tract.
- pctage65p
The percentage of residents aged 65 or older.
- Z
A transformation of exposure to TCE, specifically log(1000(TCE + 1)/pop8).
- avgidist
Average inverse distance to the nearest TCE site.
- pexpossure
- cases
The number of leukemia cases between 1978-1982.
- xm
A shifted version of x.
- ym
A shifted version of y.
- x
x-coordinate associated with the centroid of each region.
- y
y-coordinate associated with the centroid of each region.
- geometry
The geometry list column of the object.
