draw.kaplan: draw.kaplan

In averissimo/verissimo-rpackage: A lot of generic functions that can be reused

Description

Mega function that draws multiple kaplan meyer survival curves (or just 1)

Usage

draw.kaplan(chosen.btas, xdata, ydata, probs = c(0.5, 0.5),
  filename = "SurvivalCurves", save.plot = F, xlim = NULL, ylim = NULL,
  expand.yzero = F, base.directory = file.path("output", "kaplan-meier"),
  legend.outside = T)

Arguments

chosen.btas	list of testing coefficients to calculate prognostic indexes, for example “list(Age = some_vector)“
xdata	n x m matrix with n observations and m variables
ydata	Survival object
probs	How to separate high and low risk patients 50%-50% is the default, but for top and bottom 40% -> c(.4,.6)
filename	Name of file if save.plot is TRUE
save.plot	TRUE plots everything and save, FALSE only calculates p-valeu
xlim	Optional argument to limit the x-axis view
ylim	Optional argument to limit the y-axis view
base.directory	Initial directory where to store files
legend.outside	If TRUE legend will be outside plot, otherwise inside

Value

A list with plot, p-value and kaplan-meier object

Examples

data('ovarian', package = 'survival')
draw.kaplan(c(age = 1), ovarian$age, data.frame(time = ovarian$futime, status = ovarian$fustat))
draw.kaplan(c(age = 1), c(1,0,1,0,1,0), data.frame(time = runif(6), status = rbinom(6, 1, .5)))
