gplot1 {blockmodeling}R Documentation

A wrapper for funcction gplot - Two-Dimensional Visualization of Graphs

Description

The function calls function gplot from library sna with different defaults. Usefun for ploting image graphs.

Usage

gplot1(M, diag = TRUE, displaylabels = TRUE, boxed.labels = FALSE,
   loop.cex = 4, arrowhead.cex = NULL, arrowheads.fun = "sqrt",
   edge.lwd = 1, edge.col = "default", rel.thresh = 0.05, ...)
gplot2(M, uselen = TRUE, usecurve = TRUE, edge.len = 0.001,
   diag = TRUE, displaylabels = TRUE, boxed.labels = FALSE,
   loop.cex = 4, arrowhead.cex = 2.5, edge.lwd = 1,
   edge.col = "default", rel.thresh = 0.05, ...)

Arguments

M A matix (array) of a graph or set thereof. This data may be valued.
diag boolean indicating whether or not the diagonal should be treated as valid data. Set this true if and only if the data can contain loops. diag is FALSE by default.
rel.thresh real number indicating the lower relative (compared to the highest value) threshold for tie values. Only ties of value >thresh are displayed. By default, thresh=0.
displaylabels boolean; should vertex labels be displayed?
boxed.labels boolean; place vertex labels within boxes?
arrowhead.cex An expansion factor for edge arrowheads.
arrowheads.fun A function for scaling arrowheands.
loop.cex expansion factor for loops; may be given as a vector, if loops are to be of different sizes.
edge.col color for edges; may be given as a vector or adjacency matrix, if edges are to be of different colors.
edge.lwd line width scale for edges; if set greater than 0, edge widths are scaled by edge.lwd*dat. May be given as a vector or adjacency matrix, if edges are to have different line widths.
edge.len if uselen==TRUE, curved edge lengths are scaled by edge.len.
uselen boolean; should we use edge.len to rescale edge lengths?
usecurve boolean; should we use edge.curve?
... additional arguments to plot or gplot from package sna:

mode: the vertex placement algorithm; this must correspond to a gplot.layout function from package sna.

Value

Plots a graph
