plotblk: Plot a blockmodel
In concorR: CONCOR and Supplemental Functions

Description Usage Arguments Details Value Author(s) References See Also Examples

Displays a plot of a blockmodel. Based on plot.blockmodel (sna must be installed), but reformats the plot to be square and removes the mandatory title.

1	plot_blk(x, labels = FALSE, ...)

`x`	An object of class `blockmodel`
`labels`	If `TRUE`, vertex ids are displayed as row/column/diagonal labels. If `FALSE`, no node labels are shown.
`...`	Further arguments passed to or from other methods

This is a modification of the plot.blockmodel function. The original displays vertex ids as row, column, and diagonal labels, which can be unreadable for larger networks. plot.blockmodel also adds a title of the form "Relation - 1", which this version omits.

Returns NULL, invisibly.
