Find the mapping vectors for one observation or prediction.
1 2  getMap(ice, regionInfo, plotting = FALSE, main = "", myLand = land,
nSpace = 7)

ice 

regionInfo 
region information list (defaults to 
plotting 
boolean indicating if map should be plotted 
main 
string specifying the name for the plot 
myLand 

nSpace 
Spacing between points and lines that should be plotted. Defaults to every seventh point and arrow 
Often reg
, lines
, and out
are taken from a
region information list.
A region information list is a list of seven objects:
regions
, startLines
, startCoords
, out
,
lines
, dist
, loop
, and angs
. The first
of these seven items are lists giving information about each of the
regions thatwill be predicted and the seventh is a vector. The
package contains a regionInfo
object in the
regionInfo.rda
file, whichis typically what is used for all
analyis. However, it would be possible to redefine the regions if
desired by making a new regionInfo
object.
The variable regions
gives SpatialPolygons
objects
for each region. The values for startLines
and
startCoords
give the starting line from which each region is
mapped and built as a SpatialLines
object and a matrix of
coordinates respectively. For regions with loop = TRUE
, the
value for startLines
is NULL, and the value for
startCoords
is simply the coordinates for the centroid
repeatedly.
The variable out
gives a list of SpatialPolygons
objects for each region that is outside the corresponding region,
but that border the starting lines. These are used when building new
polygons to determine if points are being mapped outside the region
of interest.
The lines
list gives theSpatialLines
objects that
correspond to the line on which the regions are mapped and built.
The dist
list for each region is a vector which gives the
distances of the end and breakpoints for each of the corresponding
lines
The loop
vector gives a Boolean for each region. The value
TRUE
indicates that the lines
are mapped in a circle
around a fixed point. The value FALSE
indicates that the
lines are mapped along a line on land.
The angs
variable is a list for each region givng the angles
of the corresponding lines
List of the length of the number of regions. Each item in the list is a matrix. Each row of each matrix corresponds to a point in the region's line. The seven columns give the fixed point's xcoordinate, the fixed point's ycoordinate, the mapped point's xcoordinate, the mapped point's ycoordinate, the length of the mapping fvectors in the xdirection, the length of the vectors in the ydirection, and the angles of the mapping vectors.
