Cumulative incidence or incidence proportion is a measure of frequency, as in epidemiology, where it is a measure of disease frequency during a period of time. You can specify the following global-plot-option: ONLY specifies that only the specified plots in the list be produced; otherwise, the default survivor function plot is also displayed. Choose a cumulative incidence graph at the top right of the Change graph type dialog. View source: R/ggcompetingrisks.R.

I have two datasets D1 and D2 with eight events each (E1...E8) and five Cumulative incidence graphs. In contrast to prevalence, incidence is a measure of the occurrence of new cases of disease (or some other outcome) during a span of time.There are two related measures that are used in this regard: incidence proportion (cumulative incidence) and incidence rate. For example, suppose we want to compare the cumulative incidence curves of the 1st and 50th individuals in the brcancer dataset. Description Usage Arguments Value Author(s) Examples.

A third example is the proportion of patients who develop postoperative complications within one month of surgery. This function plots Cumulative Incidence Curves. In such a case, PROC LIFETEST creates a plot of the cumulative incidence function (CIF) estimates. Viewed 11k times 2. votes. For cuminc objects it's a ggplot2 version of plot.cuminc.For survfitms objects a different geometry is used, as suggested by @teigentler.. Usage 1 $\begingroup$ Locked. We first call the absoluteRisk function and specify the newdata argument. … Active 3 years ago.
