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.

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 The testing versions might have serious bugs or might even be outdated (use only if advised).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.

A GUI for the package blockmodeling has published for the first time in May 2022 after several months of work under my direction. This ad hoc R-Shiny GUI is meant to help users access the main functionalities of the package. However, it also allows to use other functions of the R language for statistical computing and some other packages for network analysis.

The app’s many options and ease of use make blockmodeling and basic network analysis in R easier to execute and understand than via command line. In fact, the GUI requires no coding experience, allowing researchers and laymen to access visualisations and information about blockmodeling in a simple way. Since the focus is on blockmodeling, the breadth of network analyses than can be executed is arguably not too extended. Thus, the app can find an apt use in a graduate class in quantitative methods in social science as well as in narrower courses on the clustering of networks.

The app is available in several versions:

• R package from GitHub and Zenodo;
• Stand-alone executable for Windows XP or newer (does not require R) available on GitHub in two flavours:
  • Fully executable, which runs from a .exe file. Retrievable here
  • Scripted, which runs from a visual-basic script Retrievable here
• Source code, for reviewing, testing and contributing on GitHub

To install the GUI directly from R, run the following code:

1. Ordered List ItemCheck if you need to install the `devtools` package
   if(!require(devtools))install.packages('devtools')
2. Ordered List ItemInstall the package from this repository
   devtools::install_github('FATelarico/BlockmodelingGUI')
