In many applications, such as in dose-response studies or time-course experiments, researchers are interested in testing for specific inequality constraints or patterns among the means of experimental groups. This R package is designed to test for such inequality patterns using a robust residual bootstrap based methodology which does not require the data to be normally distributed. Furthermore, this software can also handle the situation when covariates and/or random effects are present. Thus, for example, this package can be used in the context of repeated measurement designs with covariates. This package comes with a user friendly graphical interface so no programming is necessary to run this package. All the user needs to do is to provide input source of the data and select options from the interface.
