plot.dec.sim: Plot simulation results from a "dec.sim" object

In tsdf: Two-/Three-Stage Designs for Phase 1&2 Clinical Trials

Plot simulation results from a "dec.sim" object

Description

Available plot types are: true toxicity at each dose level (type = "s"); a bar plot of the probability of selecting each dose as the MTD (type = "prob"); a bar plot of the average number of patients treated at each dose level (type = "np"); and a bar plot of the average number of DLTs at each dose level (type = "dlt"). Setting type = "all" produces all four plots.

Usage

## S3 method for class 'dec.sim'
plot(
  x,
  pt,
  s = 1,
  type = c("all", "s", "prob", "np", "dlt"),
  label = TRUE,
  col = "cornflowerblue",
  text.col = "darkblue",
  cex = 1,
  ...
)

Arguments

x	An object of class "dec.sim" or "sl.sim", returned by dec.sim or sl.sim.
pt	A vector of target toxicity values, one for each scenario.
s	The scenario to plot. Defaults to 1.
type	Plot type. See the description above.
label	Logical; if TRUE, values are displayed on the plot.
col	Graphical parameter col; see par.
text.col	Color used for text labels.
cex	Graphical parameter cex; see par.
...	Arguments passed to plotting functions.

Examples

# generate decision table
dt <- dec.table(0.6,0.4,0.2,0.3,c(3,3,3))
# Simulate trials from test data
test.file <- system.file("extdata", "testS.csv", package = "tsdf")
out <- sl.sim(dt$table, test.file)
plot(out, pt=rep(0.3,2), s=1, type="all")
plot(out, pt=rep(0.3,2), s=2, type="prob")
plot(out, pt=rep(0.3,2), s=1, type="np")
plot(out, pt=rep(0.3,2), s=2, type="dlt")
