Arguments

map: An object generated with build_bmap or build_gmap.
mapkey: An object generated with build_bkey or build_gkey.

Examples

data(us_data)
data(us_geo)
poverty <- read.uv(data = us_data, estimate = "pov_rate", error = "pov_moe")

# bivariate map and key together
map <- build_bmap(data = poverty, geoData = us_geo, id = "GEO_ID",
 border = "state", terciles = TRUE)
key <- build_bkey(data = poverty, terciles = TRUE)
attach_key(map, key)
