Plot Stopping Rule (Survival Data)

Description

Display a stopping rule graphically as a curve for time-to-event data

Usage

## S3 method for class 'rule.surv'
plot(
  x,
  xlim = c(0, max(x$Rule[, 1])),
  ylim = c(0, max(x$Rule[, 2]) + 1),
  xlab = "Total Exposure Time",
  ylab = "# Events",
  ...
)

Arguments

x	A rule.surv object calculated by calc.rule.surv() function
xlim	The x limits (x1, x2) of the plot. Note that x1 > x2 is allowed and leads to a ‘reversed axis’.
ylim	The y limits of the plot.
xlab	The title for the x axis
ylab	The title for the y axis
...	Other parameters passed to the plot function.

Value

No return value; function solely generates a plot

Examples

## Not run: poc_rule = calc.rule.surv(n=50,p0=0.20,alpha=0.10,type="Pocock",tau=100)
gp_rule = calc.rule.surv(n=50,p0=0.20,alpha=0.10,type="GP",tau=100,param=c(1,1000))
plot(poc_rule)
lines(gp_rule,col="red")

## End(Not run)
