brMask: Enables Blind Review of Database

In blindreview: Enables Blind Review of Database

Enables Blind Review of Database

Description

Assigns identification randomly to one of the variables of the dataset as chosen by the user, say Treatment, and assigns random number to the observations of the dataset. Reorders the observations. A file is created so that the user can identify any outliers identified by the review in terms of their original, unchanged values.

Usage

brMask(data, blinded, verbose=TRUE) 

Arguments

data	Database to be evaluated
blinded	Character, name of variable to be blinded
verbose	TRUE causes function identifier to display before and after run

Details

The first variable of the database must be Observation. The first element of the brMask object is the database to be reviewed blindly.

Value

LIST

Masked Dataframe	Database with substitute variable and substitute observation numbers
Randomization Date	Date of randomization of blinded items
Variable	Codes for unblinding variable that was blinded
Observations	Codes for unblinding observation numbers
Call	Call to this function
