The function calls function gplot from the library sna with different defaults. Use fun for plotting image graphs.
gplot1(M, diag = TRUE,
displaylabels = TRUE, boxed.labels = FALSE,
loop.cex = 4, 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, ...)A matrix (array) of a graph or set thereof. This data may be valued.
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.
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.
Boolean; should vertex labels be displayed.
Boolean; place vertex labels within boxes.
An expansion factor for edge arrowheads.
expansion factor for loops; may be given as a vector, if loops are to be of different sizes.
Color for edges; may be given as a vector or adjacency matrix, if edges are to be of different colors.
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.
if uselen == TRUE, curved edge lengths are scaled by edge.len.
Boolean; should we use edge.len to rescale edge lengths.
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.
Plots a graph.
