Using grmap to create a redlined map of the Cleveland Area

[Liam Walker]

Hello. I am having trouble with the grmap command when creating a redlined map of the Cleveland Area. There should be 4 designations of holc_grade (1=A, 2=B, 3=C, and 4=D), but when I encode the string variables, the map only shows 1-2, 2-3, and 3-4.
I would also like 4 to have a red color, 3 to have a yellow color, 2 to have a blue color, and 1 to have a green color.

This is the code I am currently using:

ssc install spmap
ssc install shp2dta
ssc install mif2dta

cd "C:\Users\Liam\OneDrive - The College of Wooster\IS_DATA"
spshape2dta cartodb-query, replace
use cartodb-query, clear
encode holc_grade, gen(holc_n)
grmap holc_n

Thank you for any help!

use the grmap options -clmethod(unique)- and -fcolor()-

//Cleveland's City Neighborhoods (Statistical Planning Areas)
copy http://planning.clevelandohio.gov/gisdata/neighborhoods_SPAs.zip .
unzipfile neighborhoods_spas.zip
spshape2dta  "City Neighborhoods/City_Neighborhoods"
use  "City_Neighborhoods" ,clear
generate rannum = uniform()
egen group = cut(rannum), group(4)
replace group = group + 1
grmap group, clm(u) fcolor(green blue yellow red) legend(pos(6) row(1))
