It is also uniquely capable of managing complex\nscenarios, including those with delayed and missing responses,\nthereby expanding its utility in real-world applications. This\npackage offers 16 functions for simulating a variety of\nresponse adaptive randomization procedures. These functions are\nessential for guiding the selection of statistical methods in\nclinical trials, providing a flexible and effective approach to\ntrial design. Some of the detailed methodologies and algorithms\nused in this package, please refer to the following references:\nLJ Wei (1979) L. J. WEI and S.\nDURHAM (1978) Durham, S.\nD., FlournoY, N.
