## Command-line User Interface Using Pocock and Simon's Procedure with Two-Arms Case

### Description

A call to the user-iterface function used to allocate patients to one of two treatments using Pocock and Simon's method proposed by Pocock S J, Simon R (1975) <doi:10.2307/2529712>.

### Usage

PocSimMIN.ui(path, folder = "PocSimMIN")


### Arguments
