ArcMapSetup {GCDkit} | R Documentation |
This function provides a rudimentary support for drawing Arc GIS-compatible shape files (.shp).
ArcMapSetup(object, layers = NULL, map.col = NULL, map.palette = "heat.colours", labels.txt = FALSE, col.txt = "black", cex.txt = 0.5, axes = TRUE, longlat = TRUE, xlab = "Longitude", ylab = "Latitude")
object |
name of the object to be drawn, normally |
layers |
names of layers to be drawn. |
map.col |
a vector with colors specified for each of the polygons. |
map.palette |
name of a palette to fill the individual polygons by a random colour. |
labels.txt |
logical; label the individual polygons? |
col.txt |
colour of these textual labels. |
cex.txt |
relative size of these textual labels. |
axes |
logical; should be the axes drawn? |
longlat |
logical; should be long-lat grid added? |
xlab |
label for the x axis. |
ylab |
label for the y axis. |
By default, the loadData function of the GCDkit system loads a shape (*.shp)
file into a list object called GCDmap
. Each layer represents one item.
If required, the longitude-latitude grid is also drawn using the function llgridlines.
None. It just modifies properties of a Figaro object (a map).
