efftox_utility_density_plot: Plot densities of EffTox dose utilities

Description

Plot densities of EffTox dose utilities. Optionally plot only a subset of the doses by specifying the doses parameter. This function requires ggplot2 be installed.

Usage

efftox_utility_density_plot(fit, doses = NULL)

Arguments

fit

An instance of rstan::stanmodel, derived by sampling an EffTox model. Use stan::sampling(stanmodels$EffTox, data = dat).

doses

optional, vector of integer dose-levels to plot. E.g. to plot only dose-levels 1, 2 & 3 (and suppress the plotting of any other doses), use doses = 1:3

Value

an instance of ggplot. Omit assignment to just view the plot.

Examples

# NOT RUN {
dat <- efftox_parameters_demo()
dat$num_patients <- 3
dat$eff <- c(0, 1, 1)
dat$tox <- c(0, 0, 1)
dat$doses <- c(1, 2, 3)
fit <- rstan::sampling(stanmodels$EffTox, data = dat)
efftox_utility_density_plot(fit) + ggplot2::ggtitle('My doses')  # Too busy?
# Specify subset of doses to make plot less cluttered
efftox_utility_density_plot(fit, doses = 1:3) + ggplot2::ggtitle('My doses')

# }
