plotblk function

Plot a blockmodel

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.

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

Arguments

• 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

Details

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

Returns NULL, invisibly.

Examples

g1 <- matrix(c(0, 0, 0, 1, 1, 0, 1, 0, 1, 1, 0, 1, 1, 0, 1, 0), ncol = 4)
rownames(g1) <- c("a", "b", "c", "d")
colnames(g1) <- c("a", "b", "c", "d")

gl <- list(g1)
bm <- make_blk(gl, 1)[[1]]
plot_blk(bm)
