The package blockmodeling is primarily meant as an implementation of Generalized blockmodeling for valued networks. It also supports multirelational and multilevel blockmodeling. In addition, functions for computation of (dis)similarities in terms of structural and regular equivalence, plotting and other "utility" functions are provided.

If you find any bugs, please report to email: ales{dot}ziberna{at}fdv{dot}uni-lj{dot}si

A relatively tested stable version is available on CRAN. To install the package from CRAN directly within R type:
install.packages("blockmodeling").

The latest version, assumed (sometimes not sufficiently tested) to be stable which includes the latest upgrades and bug fixes is available on R-Forge repository. The package there is build during the night. There the package is available in 2 formats: Package source (.tar.gz) and Windows binary (.zip).

To install the package from R-Forge directly within R type:
install.packages("blockmodeling",repos="http://R-Forge.R-project.org")

blockmodeling R-Forge repository hosts also old and testing versions of this package. The testing versions might have serious bugs or might even be outdated (use only if advised). It also hosts some related packages.

Fabio Ashtar Telarico has created a BlockmodelingGUI R package and standalone program that represents a GUI for the package for the analysis of one-mode single-relational networks.
