  regime = NULL)

Arguments

var1	First variable to be used, required
var2	Second variable to be used, required
var3	Third variable to be used, not required
var4	Fourth variable to be used, not required

Value

A vector the same length as var1

Examples

# NOT RUN {
myData$J <- regime(myData$J, myData$J1, myData$J2, regime = c("G","R","Z","O"))
# }
