convert a shape-file into a boundary object
Converts the geographical information provided in a shape-file into a boundary object (see Ch. 5 of the Reference Manual)
shp2bnd(shpname, regionnames, check.is.in = TRUE)
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) |
Returns a boundary object, i.e. a list of polygons that form the
map. See read.bnd for more information on the format.

## read shapefile into bnd object
shpName <- sub(pattern="(.*)\\.dbf", replacement="\\1",
x=system.file("examples/northamerica_adm0.dbf",
package="BayesX"))
north <- shp2bnd(shpname=shpName, regionnames="COUNTRY")
## draw the map
drawmap(map=north)
## compare with shipped bnd file
shippedBnd <- read.bnd(system.file("examples/northamerica.bnd", package="BayesX"))
stopifnot(all.equal(north, shippedBnd))Please choose more modern alternatives, such as Google Chrome or Mozilla Firefox.
