plotGEOmap: Plot a GEO map

Description

High Level plot of GEO map

Usage

plotGEOmap(MAP, LIM = c(-180, -90, 180, 90) ,
shiftlon = 0, add = TRUE ,
NUMB = FALSE , SEL = NULL, MAPcol = NULL,
MAPstyle = NULL, border=NA,
PLOT = TRUE, PRINT=FALSE, BB = FALSE, ...)

Value

Graphical Side Effects

Arguments

MAP

Map Structure

LIM

Lat-Lon limits

add

logical, TRUE= add to existing plot

SEL

Index vector of strokes to be used in plotting, default=NULL(use all that pass other tests)

MAPcol

override color for maps

MAPstyle

override plotting style for maps

border

color, add border to polygons, NA=no border

shiftlon

degrees, rotate longitude

NUMB

logical, number the strokes on the map

PLOT

logical, TRUE=plot map, else just set up plotting area

PRINT

logical, TRUE=show selected stroke indeces on the screen(default=FALSE)

BB

logical, TRUE=add bounding box to each stroke (default=FALSE)
