st99_M_dataR Documentation

U. S. state centroid data for the states of Alaska, Hawaii, and Puerto Rico.

Description

Contains the U. S. state information for Alaska, Hawaii, and Puerto Rico needed by the satscanMapper package to create the coordinates file to be used by SaTScan (TM). The main coordinates and boundary files were modified to shift Alaska, Hawaii and Puerto Rico to better positions on the US map. To be able to create a coordinates file based on the location IDs in the *.pop and *.cas input files to SaTScan (TM), the coordinates must be based on the original Lat and Long and not the moved locations. This dataset contains the unmoved projected coordinates of the of the centroids for the three moved states. Once the analysis is completed, only the mapping coordinates are needed.

Usage

data(st99_M_data)

Format

st99.ind00 structure:

row.names

- character - 2 digit - State FIPS code.

abbr

- character - 2 character - State US PS Abbreviation.

stName

- character - State Name.

rgID

- integer - region ID number.

rgName

- character - region name. (NorthEast, South, MidWest, West, Offshore)

dvID

- integer - division ID number.

dvName

- character - division name

loc

- character - postfix file string identifying the directory/package containing the census tract boundary datasets for this state. (Regs, East, West)

county_00

- integer - number of counties in state during census year 2000.

county_10

- integer - number of counties in state during census year 2010.

tracts_00

- integer - number of census tracts in state during census year 2000.

tracts_10

- integer - number of census tracts in state during census year 2010.

change10

- logical - indicates if the state had different counties and/or boundaries in census year 2010. If FALSE, use the 2000 boundary data. If TRUE, use the supplemental 2010 boundary data. Only 3 states required a 2010 set of county boundary datasets (Alaska, Colorado, and Virginia)

c_X and c_Y

- integers - the X and Y cartesian coordinates of the center of the state.

This data.frame contains the centroid projected coordinates for Alaska, Hawaii, and Puerto Rico prior to their relocation on the map for better presentation. It has a duplicate structure and contains to the st99_data dataset to allow the state data to be easily overlaid on the normal mapping data when the coordinates file is being generated.
