The last version of the mosclust R source package is downloadable from:
http://homes.dsi.unimi.it/valenti/SW/mosclust/download/mosclust_1.0.tar.gz
To install the package on a unix/linux R environment, as usual, type as root from your shell prompt:
> R CMD INSTALL mosclust_1.0.tar.gz
This automatically installs the code and the HTML and pdf documentation. Note that mosclust requires the clusterv R package.
The mosclust reference manual in pdf format included in the package may be also downloaded from: http://homes.dsi.unimi.it/valenti/SW/mosclust/doc/mosclust-manual.pdf
