The rflexscan package provides functions and classes to analyze spatial count data using the flexible spatial scan statistic developed by Tango and Takahashi (2005). This package designed for any of the following interrelated purposes:
To evaluate reported spatial disease clusters, to see if they are statistically significant.
To test whether a disease is randomly distributed over space.
To perform geographical surveillance of disease, to detect areas of significantly high rates.
