Plot method for MAMS objects

Description

produces as plot of the boundaries.

Usage

## S3 method for class 'MAMS'
plot(
  x,
  ask = TRUE,
  which = 1:2,
  new = TRUE,
  col = NULL,
  pch = NULL,
  lty = NULL,
  main = NULL,
  xlab = "Analysis",
  ylab = "Test statistic",
  ylim = NULL,
  type = NULL,
  las = 1,
  ...
)

Arguments

x	An output object of class MAMS
ask	A logical indicating if R should wait for the next plot to be displayed.
which	A vector indicating which plot(s) to define. 1 displays the efficacy and futility limits per stage, 2 displays the efficacy nd futility probabilities per stage, 1:2 (default) displays both.
new	A logical indicating if the new plot of the futility and efficacy limits should be displayed (default='TRUE“).
col	A specification for the default plotting color (default=NULL). See par for more details.
pch	Either an integer specifying a symbol or a single character to be used as the default in plotting points (default=NULL). See par for more details.
lty	A specification for the default line type to be used between analyses (default=NULL). Setting to zero suppresses plotting of the lines. See par for more details.
main	An overall title for the plot (default=NULL).
xlab	A title for the x axis (default="Analysis").
ylab	A title for the y axis (default='"Test statistic"“).
ylim	A title for the y axis (default="Test statistic").
type	Type of plot to be used (default=NULL). See plot for more details.
las	A specification of the axis labeling style. The default 1 ensures the labels are always horizontal. See ?par for details.
...	Further arguments passed to or from other methods.

Value

Graphic output.
