vertices {parsec}

Coordinates of the vertices of the Hasse diagram, representing the input cover relation.

Description

The function computes the coordinates of the vertices of the Hasse diagram.

Usage

vertices(C, shape = c("square", "circle", "equispaced"), noise = FALSE)

Arguments

C

cover matrix, an object of class S3 cover.

shape

shape of the diagram. See details.

noise

some jittering on the x axis, so as to improve readability. Values can be boolean or positive values, to get different jittering intensities.

Details

Possible Hasse diagram shapes: square; circle; equispaced. The last option is suggested when the poset has more than one maximal or minimal elements. The function is used by the plot methods defined in the package (see plot.cover).
