SabreR
SabreR consists three components: a Sabre binary, a R wrapper that communicate with the binary file (input and output), and a short R function to print the output.
The developer of SabreR wrote the wrapper in the somewhat unconventional way, which makes table making and simulation difficult.

Statistical simulation
Chapter 7 of Data Analysis Using Regression and Multilevel/Hierarchical Models by Gelman and Hill offers good description of why use statistical simulation in quantitative research. Their R package ARM provides a good place to get started to program one's own simulation module. Of course, Zelig has already had a impressive collection of models pre-programmed; but custom programming is always more fun.

In addition, MEMISC also provides infrastructure for survey data analysis.
