plot.critFun {blockmodeling}  R Documentation 
The main function plot.mat
or plotMat
plots a (optionally partitioned) matrix.
If the matrix is partitioned, the rows and columns of the matrix are rearranged according to the partitions.
Other functions are only wrappers for plot.mat
or plotMat
for convenience when plotting the results of the corresponding functions.
The plotMatNm
plots two matrices based on M, normalized by rows and columns, next to each other. The plotArray
plots an array. plot.mat.nm
has been replaced by plotMatNm
.
