StrPBR.ui {carat}

Command-line User Interface Using Stratified Permuted Block Randomization with Two-Arms Case

Description

A call to the user-iterface function used to allocate patients to one of two treatments using stratified permuted block randomization proposed by Zelen M (1974) <doi: 10.1016/0021-9681(74)90015-0>.

Usage

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

Arguments

path

the path in which a folder used to storage variables will be created.

folder

name of the folder. If default, a folder named "StrPBR" will be created.

Details

See StrPBR.

Value

It returns an object of class "carseq".

The function print is used to obtain results. The generic accessor functions assignment, covariate, cov_num, cov_profile and others extract various useful features of the value returned by StrPBR.ui.

Note

This function provides a command-line interface and users should follow the prompts to enter data including covariates as well as levels for each covariate, block size bsize and the covariate profile of the new patient.
