plot.diagRelUtility {optimalThreshold}

Plot the decision curves of a diagnostic marker

Description

Plot the decision curves of a diagnostic marker

Usage

## S4 method for signature 'diagRelUtility'
plot(x, y, main = "Decision curves",
  lty = 1, lwd = 1, xlim = range(x@r), ylim = c(min(x@U,
  x@UNoTreat, x@UTreatAll), max(x@U, x@UNoTreat, x@UTreatAll)),
  ylab = "Expected benefit", xlab = "r", col.U = "black",
  col.UNoTreat = "blue", col.UTreatAll = "green", ...)

Arguments

x

a diagRelUtility object.

y

unused parameter.

main

an overall title for the plot.

lty

the line type. Line types can either be specified as an integer (0=blank, 1=solid (default), 2=dashed, 3=dotted, 4=dotdash, 5=longdash, 6=twodash) or as one of the character strings "blank", "solid", "dashed", "dotted", "dotdash", "longdash", or "twodash", where "blank" uses 'invisible lines' (i.e., does not draw them).

lwd

the line width, a positive number, defaulting to 1. The interpretation is device-specific, and some devices do not implement line widths less than one. (See the help on the device for details of the interpretation).

xlim

the x limits of the plot.

ylim

the x limits of the plot.

ylab

a label for the y axis.

xlab

a label for the x axis

col.U

color of the utility curve for the marker-based strategy.

col.UNoTreat

color of the utility curve for the "No Treat" strategy.

col.UTreatAll

color of the utility curve for the "Treat All" strategy.

...

other graphical parameters.

Value

None
