Utilities: coo.plot: Plots sets of shapes.

Description

coo.plot is a simple wrapper for plotting shapes. It basically tunes plot standard function to display single shapes as polygons, within a standardised plotting area. coo.draw simply adds a shape on the active plot. coo.list.panel plots a list of shapes.

Usage

coo.plot(coo=NA, col="#70809033",
		border="#708090EE", xlim=c(-1, 1), ylim=c(-1, 1), points=TRUE, first.point=TRUE,
		points.col=border, pch=20, cex=0.25, main, ...)

coo.draw(coo = NA, col = "#70809033",
		border = "#708090EE", points = TRUE, first.point=TRUE,
		points.col = border, pch = 20, cex = 0.25,  ...)

coo.list.panel(coo.list, dim,
		byrow = TRUE, fromtop = TRUE,
		mar = rep(0, 4), cols, borders, density = NULL, angle = 45)

Arguments

coo

A list or a matrix of coordinates.

col

A color to fill the shape polygon.

border

A color for the shape border.

xlim

If coo.plot is called and coo is missing, then a vector of length 2 specifying the ylim of the ploting area.

ylim

If coo.plot is called and coo is missing, then a vector of length 2 specifying the ylim of the ploting area.

points

logical. Whether to display points. If missing and number of points is < 100, then points are plotted.

first.point

logical. Whether to display the first point.

points.col

The color for plotting points.

pch

The pch for points.

cex

The cex for points.

main

character. A title for the plot.

...

Additional parameters for drawing the first point.

coo.list

A list of coordinates, such as those in the @coo slot of Coo objects.

dim

A vector of the form (nb.row, nb.cols) to specify the panel display. If missing, shapes are arranged in a square.

byrow

logical. Whether to succesive shape by row or by col.

fromtop

logical. Whether to display shapes from the top of the plotting region.

mar

A vector to define margins.

cols

A vector of colors to fill shapes.

borders

A vector of colors to draw shape borders.

density

A vector for density of shading lines. See polygon

angle

A vector for shading lines.

coo.plot(bot@coo[[1]])
coo.list.panel(bot@coo)
