R: Add carryover dummy variables

createCarry {CrossCarry}

R Documentation

Add carryover dummy variables

Description

Create dummy variables associated with first-order carryover effect in a Crossover Design

Usage

createCarry(data, treatment, period, id, carrySimple = TRUE)

Arguments

`data`	A data frame with the variables of the crossover experimental design
`treatment`	A character string specifying the name of vector with the treatment applied at each observation of the crossover experimental design
`period`	A character string specifying the name of vector with the observation period of the responses of the crossover experimental design
`id`	A character string specifying the name of vector which identifies the experimental units.
`carrySimple`	`TRUE` = simple carry-over, where the residual effect of a treatment affects equally each of the treatments that are preceded by it, and `FALSE` = carry-over complex, where the residual effect of the treatment affects each of the other treatments differently.

Value

data A data frame with all the variables of the crossover experimental design and the carryover variables

carryover The new carryover variables

Examples

data(Water)
carryover <- createCarry(data=Water,
                         treatment = "Treatment", id = "ID",
                         period = "Period", carrySimple = FALSE)
carryover$carryover
carryover$data
