# plot.etmCIF: Plot cumulative incidence functions In etm: Empirical Transition Matrix

## Description

Plot function for `etmCIF` objects. The function plots cumulative incidence curves, possibly with pointwise confidence intervals.

## Usage

 ```1 2 3 4 5 6``` ```## S3 method for class 'etmCIF' plot(x, which.cif, xlim, ylim, ylab = "Cumulative Incidence", xlab = "Time", col = 1, lty, lwd = 1, ci.type = c("none", "bars", "pointwise"), ci.fun = "cloglog", ci.col = col, ci.lty = 3, legend = TRUE, legend.pos, curvlab, legend.bty = "n", pos.ci = 27, ci.lwd = 3, ...) ```

## Arguments

 `x` A `etmCIF` object `which.cif` A numeric vector indicating which CIFs should be plotted. When missing, only the CIF of interest is plotted (determined through the `failcode` argument in `etmCIF`.) `xlim` x-axis limits for the plot. By default, `c(0, max(time))` `ylim` y-axis limits. Default is `c(0, 1)` `ylab` Label for y-axis. Default is `"Cumulative Incidence"` `xlab` Label for x-axis. Default is "Time" `col` Vector describing colours used for the CIF curves. Default is black `lty` Vector of line type `lwd` Thickness of the lines `ci.type` One of ```c("none", "bars", "pointwise")```. `none` plots no confidence interval, `bars` plots the confidence intervals in the form of a segment for one time point, and `pointwise` draws pointwise confidence intervals for the whole follow-up period. `ci.fun` Transformation used for the confidence intervals. Default is "clolog", and is a better choice for cumulative incidences. Other choices are "log" and "log-log" `ci.col` Colour for the pointwise confidence interval curves. Default is same as the CIF curves `ci.lty` Line type for the confidence intervals. Default is 3 `legend` Logical. Whether to draw a legend. Default is `TRUE` `legend.pos` A vector giving the legend's position. See `legend` for further details `curvlab` A character or expression vector to appear in the legend. Default is CIF + event label `legend.bty` Box type for the legend. Default is none ("n") `pos.ci` If `ci.type = "bars"`, vector of integers indicating at which time point to put the confidence interval bars. Default is 27 `ci.lwd` Thickness of the confidence interval segment (for `ci.type = "bars"`) `...` Further graphical arguments

## Details

The function relies on `plot.etm` and `lines.etm` with more or less the same options. Exception is the drawing of the confidence intervals, for which several displays are possible.

## Value
