An R Package for Generalized and Classical Blockmodeling of Valued Networks
Main page

Basic description
The package blockmodeling is primarily meant as an implementation of Generalized blockmodeling for valued networks. It aslo 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.

The lates version (which does 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:

Fairly recent version 1.0.0 is available on CRAN. However, this version does not include all patches, upgrades or bug fixes. This version of the blockmodeling package can be therefore instaled using install.packages using the CRAN repository by typing within R:

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