plot.VTDEC: Plot decision map

In visit: Vaccine Phase I Design with Simultaneous Evaluation of Immunogenicity and Toxicity

Plot decision map

Description

Plot a decision map based on a class VTDEC object that contains the current posterior analysis results

Usage

## S3 method for class 'VTDEC'
plot(x, margin = 0.003, nms = c("TT", "NME", "SE",
  "UN"), col.reg = "pink", col.prob = "blue", cex.prob = 0.9,
  cex.nms = 1, ...)

Arguments

x	A class VTDEC list generated by vtDecMap
margin	Margin between regions in the decision map
nms	Labels of the regions on a decision map. Defaults are: TT:Too Toxic NME:No More Effective SE:Safe and Effective UN:Uncertain
col.reg	Background color of the selected region
col.prob	Text color of the selected region.
cex.prob	Text size of the probabilities
cex.nms	Text size of the region labels
...	Optional arguments for plot.

Examples

etas       <- c(0.1, 0.3)
dec.cut    <- c(0.6,0.6,0.6)
cur.obs.y  <- c(3, 2, 1, 1)
prev.obs.y <- c(5, 2, 0, 0)
rst.inter  <- vtInterim(cur.obs.y,  prev.obs.y = prev.obs.y,
                        prob.mdl = "NONPARA", etas = etas, dec.cut = dec.cut,
                        nsmp = 2000);
plot(rst.inter)
