Usage
plotRects(R, grid=FALSE, grid.lty=3, grid.col="lightgray", density=NULL,
angle=45, col=NA, border=rainbow(nrow(R)), lty=1, lwd=1,
add=FALSE, xlim=NULL, ylim=NULL, xlab="", ylab="", main="", sub="")Arguments
R
A nx4 matrix of rectangles. Each row corresponds to an
rectangle, represented as (x1,x2,y1,y2). The point (x1,y1) is
the lower left corner of the rectangle and the point (x2,y2) is the
upper right corner of the rectangle.
grid
Logical, indicating if a grid should be drawn.
The default value is FALSE.
grid.lty
Line type of the grid lines. The default value is 3=dotted.
grid.col
Line color of the grid lines. The default value is light
gray.
density
Density
of shading lines for the rectangles, in lines per inch.
The default value is NULL, meaning that
no shading lines are drawn. A zero value of density means no shading
lines whereas negative values (and NA) suppress shading (and
angle
Angle (in
degrees) of the shading lines.
col
Color(s) to
fill or shade the rectangles with. The default NA (or also NULL) means
do not fill, i.e., draw transparent rectangles, unless density is
specified.
border
Color for
rectangle borders. Use border = NA to omit borders. If there are shading
lines, border = TRUE means use the same color for the border as for the
shading lines. The default value is rainbow(n): a vector of n contiguous
lty
Line type for
borders and shading of the rectangles. The default value is 1="solid".
lwd
Line width for
borders and shading of the rectangles. The default value is 1.
add
Logical, indicating if the rectangles should be added
to an existing plot. The default value is FALSE.
xlim
Range of the x-axis. The default value is the range of
x-coordinates of the rectangles.
ylim
Range of the y-axis. The default value is the range of
y-coordinates of the rectagnles.
xlab, ylab
Labels of the x and y axis. The default values are empty.
main
Title of the plot. The default value is empty.
sub
Sub title of the plot. The default value is empty.
