Add point-wise confidence limits to the graphs of Kaplan-Meier and Aalen-Johansen estimates.

This function is invoked and controlled by plot.prodlim.

confInt(ci, citype, col, lty, lwd, density = 55, ...)

Arguments

ci: A data.table with columns time, lower and upper.
citype: If "shadow" then confidence limits are drawn as colored shadows. Otherwise, dotted lines are used to show the upper and lower confidence limits.
col: the colour of the lines.
lty: the line type of the lines.
lwd: the line thickness of the lines.
density: For citype="shadow", the density of the shade. Default is 55 percent.
...: Further arguments that are passed to the function segments if type=="bars" and to lines else.

Nil

This function should not be called directly. The arguments can be specified as Confint.arg in the call to plot.prodlim.
