plot.ewoc2simu: EWOC for 2 drugs combination trial design characteristics

In EWOC2: Escalation with Overdose Control using 2 Drug Combinations

Description

Function to plot the trial design characteristics from EWOC 2 drugs combination simulation results

Usage

## S3 method for class 'ewoc2simu'
plot(x, type = "MTD", conf.reg=0.9, plot.figure="Y",...)

Arguments

x	an object of class "ewoc2simu", usually a result of a call to ewoc2simu
type	a character indicating the type of plots a user requests, could be "MTD", "bias", or "percent". For discrete simulations, "bias" is not available
conf.reg	confidence level that controls the region of the doses from the last trial in the MTD plot
plot.figure	a character indicating whether user wants the plot, 'Y' would be yes, otherwise would be no. It's mainly for internal uses
...	arguments passed to or from methods

a10=1,b10=1, a00=1,b00=1,a=0.8,b=0.0384)

print(test1)
plot(test1, type="MTD")
plot(test1, type="bias")
plot(test1, type="percent")
