MRPWorkflow-method-estimate_map: Create a choropleth map of MRP estimates

In shinymrp: Interface for Multilevel Regression and Poststratification

Create a choropleth map of MRP estimates

Description

The ⁠$estimate_map()⁠ method creates interactive choropleth maps that show MRP estimates by geographic region. This method cannot be used if either the sample or the poststratification data contains no geographic information. Check out the More examples of R6 classes vignette for usage examples.

Usage

estimate_map(
  model,
  geo = NULL,
  time_index = NULL,
  interval = 0.95,
  file = NULL
)

Arguments

model	Fitted MRPModel object
geo	Character string specifying the geographic level for mapping. Options include geography for data linking and those at larger scales. A "linking" geography is required to use this method. It is either specified as geo in the ⁠$link_acs()⁠ method or the smallest common geographic scale between the sample data and the custom poststratification data input using ⁠$load_pstrat()⁠.
time_index	Integer specifying the time index for time-varying data.
interval	Confidence interval (a numeric value between 0 and 1) or standard deviation ("1sd" or "2sd") for the estimates (default is 0.95).
file	Optional file path with .html extension to save the interactive map. Expand the hamburger menu in the top right corner of the map to access other export options.

Value

A highcharter map object showing MRP estimates by geography.
