plot,Samples,DualEndpoint-method | R Documentation |
When we have the dual endpoint model, also the dose-biomarker fit is shown in the plot
## S4 method for signature 'Samples,DualEndpoint' plot(x, y, data, extrapolate = TRUE, showLegend = FALSE, ...)
x |
the |
y |
the |
data |
the |
extrapolate |
should the biomarker fit be extrapolated to the whole dose grid? (default) |
showLegend |
should the legend be shown? (not default) |
... |
additional arguments for the parent method
|
This returns the ggplot
object with the dose-toxicity and dose-biomarker model fits
