Usage

simPats(npat, factList)

Arguments

npat	The number of patients to simulate.
factList	A list containing either functions that will be called or named vectors containing relative proportions, for factors.

Value

A data.frame with npat rows and one column for each variable given in the factList.

Examples

coh1 =  list(center=c(C1=.4, C2=.2, C3=.1, C4=.3),
             sex=c(Male=.5, Female=.5),
             age = function(x) runif(x, min=50, max=70))
simDat = simPats(100, coh1)
simDat[1:5,]
table(simDat[,1])
