Mapping estimates for svysae object

Usage

mapEstimates(x, geo.data, variable, viridis.option = "viridis")

Arguments

x: syvsae object
geo.data: sf object containing polygon data for the small areas. One of the columns should be named domain and contain the domain labels.
variable: The posterior summary variable to plot. May be one of "median", "mean", or "var".
viridis.option: viridis color scheme

Value

ggplot containing map of small area posterior summary statistics

Examples

if (FALSE) { # \dontrun{
data(DemoData2)
data(DemoMap2)
library(survey)
des0 <- svydesign(ids = ~clustid+id, strata = ~strata,
                  weights = ~weights, data = DemoData2, nest = TRUE)
Xmat <- aggregate(age~region, data = DemoData2, FUN = mean)
geo.data <- sf::st_as_sf(DemoMap2$geo)
