Spatial analysis function

[dcpcamara]

This function pops a Shiny dashboard so that the user can performe an exploratory spatial analysis on her/his dataset. It needs a shapefile, a geopackage file, a RDS file, or a sf/sp object. The functions automatically converts the spatial polygon file into WGS84 (for better coding and integration into existing tools/packages). So far:

• The function allows user to create and explore different spatial contiguity strategies (Queen, Rook, KNN and distance-based - this one on degrees).

In the future:

• Find a reliable way to convert degrees to meters/kilometers.
• Add choropleth map for the chosen variable.
• Add empirical bayesian estimates (global and local) for a chosen variable.
• Add global Moran test for spatial dependency.
• Add LISA test.
• Add GI test for clustering.
• Add retrospective poisson cluster detection model (null model only!) via Kulldorf (1997).
