stateTable_-: A function to change the state of a Randomizer

In SRS: Subject Randomization System

Description

This function allows you to set the slot named stateTable of an object of class PocockSimonRandomizer to a value. This allows you to start the randomization from arbitrary points in time.

Usage

stateTable(x)<- value

Arguments

x	An object of class PocockSimonRandomizer
value	a matrix of marginal counts of treatment allocations by the levels of each factor. It is important to ensure that the dimensions match with the experimental setup. At the moment, no checks are done, although that might change in the future.

Examples

state.matrix <- matrix (c(9,8,8,9,8,4,5,
                       10,7,6,11,8,5,4,
                       9,7,7,9,8,3,5), nrow=3, byrow=TRUE)

rownames(state.matrix) <- c("Tr1", "Tr2", "Tr3")
colnames(state.matrix) <- c("F1:1", "F1:2", "F2:1", "F2:2", "F3:1", "F3:2", "F3:3")

expt <- ClinicalExperiment(number.of.factors = 3,
                           number.of.factor.levels = c(2, 2, 3),
                           number.of.treatments = 3)

y <- new("PocockSimonRandomizer", expt, as.integer(12345))

y@stateTable <- state.matrix
