plot.emaxsim {clinDR}R Documentation

Plot the output of emaxsim

Description

A Q-Q plot of the dose response estimate of the mean at a specified dose minus the population value divided by the standard error of the estimator (computed using the delta method). Estimates based on alternative models when the Emax estimation fails are highlighted in red.

Usage

## S3 method for class 'emaxsim'
plot(x, id = x$idmax, plotDif= TRUE, ...)

Arguments

x

Output of emaxsim

id

Index of the dose to be assessed (placebo index=1).

plotDif

If true (default), the estimates and population values are differences with placebo. IF false, absolute dose response values are used.

...

Optional parameters passed to the plotting function

Value

No output is returned.
