plot.sociomatrix {sna}R Documentation

Plot Matrices Using a Color/Intensity Grid

Description

Plots a matrix, m, associating the magnitude of the i,jth cell of m with the color of the i,jth cell of an nrow(m) by ncol(m) grid.

Usage

plot.sociomatrix(x, labels=NULL, drawlab=TRUE, diaglab=TRUE, 
    drawlines=TRUE, xlab=NULL, ylab=NULL, cex.lab=1, ...)

Arguments

x an input graph.
labels a list containing the vectors of row and column labels (respectively); defaults to numerical labels.
drawlab logical; add row/column labels to the plot?
diaglab logical; label the diagonal?
drawlines logical; draw lines to mark cell boundaries?
xlab x axis label.
ylab y axis label.
cex.lab optional expansion factor for labels.
... additional arguments to plot.

Details

plot.sociomatrix is particularly valuable for examining large adjacency matrices, whose structure can be non-obvious otherwise.

Value

None
