Description

Generate a plot representing the observed data and dose escalation decisions.

Usage

vtTrack(obs.all, cex.txt = 0.9, decision = 1, max.level = NULL,
  letters = c("E", "C", "S"), colors = c("green", "yellow", "red"),
  height = 0.5, end.width = 2, end.height = height,
  cex.roman = 0.9, cex.end = 0.9, ...)

Arguments

obs.all	All observations collected in a matrix with 5 columns. Column 1 is the index of interim analysis starting from 1. Columns 2-5 correspond to columns 1-4 in obs.y for vtPost.
cex.txt	Text size of numbers in the plot
decision	Dose escalation decision. The options are 1: Escalate 2: Continue at the same level 3: Stop the trial
max.level	Maximum number of dose levels shown in the plot
letters	Labels for dose escalation actions 1-3. Default values are "E", "C", "S"
colors	Possible colors in the last action box
height	Height of each individual box
end.width	Width of the last action box
end.height	Height of the last action box
cex.roman	Text size of the roman numerals
cex.end	Text size of the letter in the last action box
...	Optional arguments for plot.

Examples

obs.all  <- rbind(c(1, 5, 2, 0, 0),
                  c(2, 3, 4, 0, 0),
                  c(3, 1, 6, 0, 0));
vtTrack(obs.all, end.width = 0.8, max.level = 3, decision = 3);
