gplot1 {blockmodeling} | R Documentation |
The function calls function gplot
from library sna with different defaults. Usefun for ploting image graphs.
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, ...)
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 .
