shp2bnd {R2BayesX}

convert a shape-file into a boundary object

Description

Converts the geographical information provided in a shape-file into a boundary object (see Chapter 5 of the BayesX Reference Manual)

Usage

  shp2bnd(shpname, regionnames, check.is.in = TRUE)

Arguments

shpname

base filename of the shape-file (including path)

regionnames

either a vector of region names or the name of the variable in the dbf-file representing these names

check.is.in

test whether some regions are surrounded by other regions (FALSE speeds up the execution time but may result in a corrupted bnd-file)

Value

Returns a boundary object, i.e. a list of polygons that form the map. See read.bnd for more information on the format.

## draw the map
plotmap(north)
