There is a package called QCA which (in its first release) performs only
crisp set analysis. I am currently adapting a Graphical User Interface, but
the functions are nevertheless usefull.
For fuzzy set analysis, please consider Charles Ragin's web site
http://www.u.arizona.edu/%7Ecragin/fsQCA/index.shtml
which offers a software (still not complete, though). Also to consider
is a good software called Tosmana (http://www.tosmana.org/) which does
multi-value
QCA.
I am considering writing the inclusion algorithms in the next releases of  my
package, but it is going to take a little while. Any contributions and/or
feedback are more than welcome.

I hope this helps you,
Adrian
