Examples

# Baseline data definitions

def <- defData(varname = "x1", formula = .5, dist = "binary")
def <- defData(def,varname = "x2", formula = .5, dist = "binary")
def <- defData(def,varname = "grp", formula = .5, dist = "binary")

# Survival data definitions

sdef <- defSurv(varname = "survTime", formula = "1.5*x1",
                scale = "grp*50 + (1-grp)*25", shape = "grp*1 + (1-grp)*1.5")

sdef <- defSurv(sdef, varname = "censorTime", scale = 80, shape = 1)

sdef

# Baseline data definitions

dtSurv <- genData(300, def)

# Add survival times

dtSurv <- genSurv(dtSurv, sdef)

head(dtSurv)
