gplot1 function

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

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,
  ...
)

Arguments

• M: A matrix (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.

• displaylabels: Boolean; should vertex labels be displayed.

• boxed.labels: Boolean; place vertex labels within boxes.

• loop.cex: An expansion factor for loops; may be given as a vector, if loops are to be of different sizes.

• 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.col: Color for edges; may be given as a vector or adjacency matrix, if edges are to be of different colors.

• 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.

• ...: Additional arguments to plot or link{sna::gplot}:

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

• uselen: Boolean; should we use edge.len to rescale edge lengths.

• usecurve: Boolean; should we use edge.curve.

• edge.len: If uselen == TRUE, curved edge lengths are scaled by edge.len.

• arrowhead.cex: An expansion factor for edge arrowheads.

Returns

Plots a graph.
