Plots a Kaplan Meier survival curve with number at risk table

Description

Creates Kaplan-Meier survival curves, prints a number at risk table and calculates & plots a Cox-PH LRT p-value. Median event times are indicted by addiditional lines.

Usage

plotKM(
  srv,
  grp,
  xlim = NULL,
  col = NULL,
  xyleg = NULL,
  offsetNRisk = -0.2,
  yDelta = 0.1,
  nRiskCat = 4,
  pval = NULL,
  mar = NULL,
  subject = NULL,
  dist = NULL,
  MDPI = F,
  ...
)

Arguments

srv	Survival obejct as obtained by survival::Surv()
grp	grouping variable
xlim	xlim range to plot. Default: 0-max time included in the srv object
xyleg	vector contaning x,y coordinates to the legend
offsetNRisk	offset in y dimensions to move the number at risk table
yDelta	y difference between rows of the number at risk table
nRiskCat	Number of breaks of the number a risk table
pval	xy coordinates of where to plot the pvalue
mar	margin parameter, calculated internally (default). Not used if mar is set to anything different from NULL
MDPI	if set to T, adhere to MDPI requirements

Examples

require(survival)
time <- c(10,7,8,4,11,14)
status <- c(1,1,1,0,1,0)
srv <- Surv(time, status)
	grp <- c(rep("A", 3), rep("B", 3))
	plotKM(srv, grp)
